Example Question #1883 : Operations

Find the sum of \(\displaystyle 45\)\(\displaystyle 79\), and \(\displaystyle 12.3\).

Possible Answers:

\(\displaystyle 13.63\)

\(\displaystyle 247\)

\(\displaystyle 136.3\)

\(\displaystyle 1363\)

\(\displaystyle 137.6\)

Correct answer:

\(\displaystyle 136.3\)

Explanation:

To find the sum, you need to add. Line up all numbers vertically. Since one number has a decimal in the tenths place, be extra careful to line up the digits correctly. To help you, add a zero in the tenths place at the end of the other two numbers so that all digits line up correctly.

\(\displaystyle \begin{matrix} &45.0 \\ & 79.0\\ + & 12.3\\ & 136.3 \end{matrix}\)

When adding the ones place, we get \(\displaystyle 16\). The \(\displaystyle 6\) goes to the answer, and we need to carry the \(\displaystyle 1\) to the tens. The tens place adds up to \(\displaystyle 13\) with the extra \(\displaystyle 1\).

The sum is \(\displaystyle 136.3\).

Example Question #1041 : How To Add

Uchenna has \(\displaystyle \$156\)in her piggy bank. On Christmas, Uchenna receives another \(\displaystyle \$50\) from her grandmother and \(\displaystyle \$25\) from her uncle. How much total money does Uchenna have now?

Possible Answers:

\(\displaystyle \$276\)

\(\displaystyle \$146\)

\(\displaystyle \$261\)

\(\displaystyle \$231\)

\(\displaystyle \$303\)

Correct answer:

\(\displaystyle \$231\)

Explanation:

Since Uchenna is gaining money, we need to add all three values together.

\(\displaystyle \$156+\$50+\$25=\$231\)

Example Question #1042 : How To Add

A mailman has \(\displaystyle 16\) items to deliver and then learns he has to deliver an additional \(\displaystyle 9\) items. What is the square root of the total amount of items he now has to deliver?

Possible Answers:

\(\displaystyle 25\)

\(\displaystyle 4\)

\(\displaystyle 3\)

\(\displaystyle 5\)

\(\displaystyle 26\)

Correct answer:

\(\displaystyle 5\)

Explanation:

\(\displaystyle 16 + 9 = 25\). Take the square root of \(\displaystyle 25\) to obtain \(\displaystyle 5\).

Example Question #1891 : Operations

Pete baked \(\displaystyle 13\) cookies today and \(\displaystyle 9\) cookies yesterday. How many cookies did Pete makie in total over those two days?

Possible Answers:

\(\displaystyle 22\)

\(\displaystyle 18\)

\(\displaystyle 19\)

\(\displaystyle 21\)

\(\displaystyle 20\)

Correct answer:

\(\displaystyle 22\)

Explanation:

You add the number of cookies made in each day, so

\(\displaystyle 13+9=22\)

Example Question #1044 : How To Add

Find the sum of \(\displaystyle 23\) and \(\displaystyle 47\).

Possible Answers:

\(\displaystyle 60\)

\(\displaystyle 67\)

\(\displaystyle 76\)

\(\displaystyle 70\)

\(\displaystyle 80\)

Correct answer:

\(\displaystyle 70\)

Explanation:

To find the sum, we need to add the given numbers together.

Adding the ones place equals \(\displaystyle 10\).

\(\displaystyle 3+7=10\).

Carry the \(\displaystyle 1\) to the tens place. Adding the tens place then equals \(\displaystyle 7\).

\(\displaystyle 1+2+4=7\)

Together, this gives us \(\displaystyle 70\).

\(\displaystyle 23 + 47 = 70\)

Example Question #1045 : How To Add

Amy went to the store to buy three things.

\(\displaystyle 1\) avocado costs her \(\displaystyle \$1.50\).

\(\displaystyle 1\) carton of milk costs her \(\displaystyle \$3.85\).

\(\displaystyle 1\) bag of marshmallows costs her \(\displaystyle \$2.30\).

How much will her grocery bill be?

Possible Answers:

\(\displaystyle \$8.75\)

\(\displaystyle \$7.65\)

\(\displaystyle \$5.76\)

\(\displaystyle \$7.56\)

\(\displaystyle \$6.57\)

Correct answer:

\(\displaystyle \$7.65\)

Explanation:

Add up the cost of the items.

\(\displaystyle 1.50 + 3.85 + 2.30 = 7.65\)

Amy will need \(\displaystyle \small \$7.65\) to buy all three items.
