Example Question #4561 : Numbers And Operations
Round to the nearest ten.
When we round a number to the nearest ten we look to the ones place to tell us if we round up or down.
If the number in our ones place is or greater, we round up. If the number in the ones place is
or less, we round down. When we round up, the number in the tens place increases by
and all the other numbers to the right become
. When we round down, the number in the tens place stays the same and all the other numbers to the right become
.
In this case, is greater than
so our rounded number is
Example Question #201 : Number & Operations In Base Ten
Round to the nearest ten.
When we round a number to the nearest ten we look to the ones place to tell us if we round up or down.
If the number in our ones place is or greater, we round up. If the number in the ones place is
or less, we round down. When we round up, the number in the tens place increases by
and all the other numbers to the right become
. When we round down, the number in the tens place stays the same and all the other numbers to the right become
.
In this case, is greater than
so our rounded number is
Example Question #71 : Round Multi Digit Numbers: Ccss.Math.Content.4.Nbt.A.3
Round to the nearest hundred.
When we round a number to the nearest hundred we look to the tens place to tell us if we round up or down.
If the number in our tens place is or greater, we round up. If the number in the tens place is
or less, we round down. When we round up, the number in the hundreds place increases by
and all the other numbers to the right become
. When we round down, the number in the hundreds place stays the same and all the other numbers to the right become
.
In this case, is less than
so our rounded number is
Example Question #1 : Use Place Value Understanding And Properties Of Operations To Perform Multi Digit Arithmetic
Solve:
We can make a rectangular array using squares to help us solve this problem. Our multiplication problem is ; therefore, the rectangular array should have
squares across the top row and
squares down the first column. The rectangular array should look like the image below:
We can count the squares to find our answer. The correct answer is is
In order to solve this problem using multiplication, we must multiply the multiplier by each digit of the multiplicand to get the answer, which is called the product.
For this problem, is the multiplier and
is the multiplicand.
