Example Questions

Example Question #31 : Round Decimals: Ccss.Math.Content.5.Nbt.A.4

Round \(\displaystyle 621.222\) to the nearest hundredth.

 

 

Possible Answers:

\(\displaystyle 621.23\)

\(\displaystyle 621.3\)

\(\displaystyle 621.22\)

\(\displaystyle 621.1\)

\(\displaystyle 621.2\)

Correct answer:

\(\displaystyle 621.22\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 621.22{\color{Blue} 2}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 2\) is less than \(\displaystyle 5\) so our rounded number is \(\displaystyle 621.220\) or \(\displaystyle 621.22\)

Example Question #32 : Round Decimals: Ccss.Math.Content.5.Nbt.A.4

Round \(\displaystyle 794.162\) to the nearest hundredth.

 

 

Possible Answers:

\(\displaystyle 794.16\)

\(\displaystyle 794.14\)

\(\displaystyle 794.2\)

\(\displaystyle 794.15\)

\(\displaystyle 794.17\)

Correct answer:

\(\displaystyle 794.16\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 794.16{\color{Blue} 2}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 2\) is less than \(\displaystyle 5\) so our rounded number is \(\displaystyle 794.160\) or \(\displaystyle 794.16\)

Example Question #33 : Round Decimals: Ccss.Math.Content.5.Nbt.A.4

Round \(\displaystyle 865.327\) to the nearest hundredth.

 

 

Possible Answers:

\(\displaystyle 865.3\)

\(\displaystyle 865.2\)

\(\displaystyle 865.33\)

\(\displaystyle 865.1\)

\(\displaystyle 865.4\)

Correct answer:

\(\displaystyle 865.33\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 865.32{\color{Blue} 7}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 7\) is greater than \(\displaystyle 5\) so our rounded number is \(\displaystyle 865.330\) or \(\displaystyle 865.33\)

Example Question #34 : Round Decimals: Ccss.Math.Content.5.Nbt.A.4

\(\displaystyle 981.23\)

\(\displaystyle 981.2\)

\(\displaystyle 981.24\)

\(\displaystyle 981.22\)

Correct answer:

\(\displaystyle 981.23\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 981.23{\color{Blue} 1}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 1\) is less than \(\displaystyle 5\) so our rounded number is \(\displaystyle 981.230\) or \(\displaystyle 981.23\)

\(\displaystyle 573.74\)

\(\displaystyle 573.8\)

\(\displaystyle 573.6\)

\(\displaystyle 573.75\)

\(\displaystyle 573.7\)

Correct answer:

\(\displaystyle 573.75\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 573.74{\color{Blue} 9}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 9\) is greater than \(\displaystyle 5\) so our rounded number is \(\displaystyle 573.750\) or \(\displaystyle 573.75\)

Example Question #36 : Round Decimals: Ccss.Math.Content.5.Nbt.A.4

\(\displaystyle 184.38\)

\(\displaystyle 200\)

\(\displaystyle 184.4\)

Correct answer:

\(\displaystyle 184.38\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 184.37{\color{Blue} 6}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).

In this case, \(\displaystyle 6\) is greater than \(\displaystyle 5\) so our rounded number is \(\displaystyle 184.380\) or \(\displaystyle 184.38\)

\(\displaystyle 295.1\)

\(\displaystyle 295.13\)

\(\displaystyle 295.14\)

\(\displaystyle 295.2\)

\(\displaystyle 295.15\)

Correct answer:

\(\displaystyle 295.14\)

Explanation:

When we round a number to the nearest hundredth we look to the thousandths place to tell us if we round up or down.

\(\displaystyle 295.14{\color{Blue} 1}\)

If the number in our thousandths place is \(\displaystyle 5\) or greater, we round up. If the number in the thousandths place is \(\displaystyle 4\) or less, we round down. When we round up, the number in the thousandths place increases by \(\displaystyle 1\) and all the other numbers to the right become \(\displaystyle 0\). When we round down, the number in the thousandths place stays the same and all the other numbers to the right become \(\displaystyle 0\).
