Example Question #881 : Operations

Mary is \(\displaystyle 8\) inches taller than her sister Kristen. If Kristen is \(\displaystyle 45\) inches tall, how tall is Mary?

Possible Answers:

\(\displaystyle 55\ inches\)

\(\displaystyle 37\ inches\)

\(\displaystyle 50\ inches\)

\(\displaystyle 53\ inches\)

Correct answer:

\(\displaystyle 53\ inches\)

Explanation:

To find Mary's height, you must add Kristen's height to the difference of height between the sisters:

\(\displaystyle 45+8=53\ inches\)

Example Question #882 : Operations

Add: \(\displaystyle 82+71+49\)

Possible Answers:

\(\displaystyle 199\)

\(\displaystyle 212\)

\(\displaystyle 189\)

\(\displaystyle 202\)

Correct answer:

\(\displaystyle 202\)

Explanation:

\(\displaystyle 82+71+49\)

You first must add the ones place: \(\displaystyle 2+1+9=12\).

You leave the \(\displaystyle 2\) and carry the \(\displaystyle 1\) to the tens place: \(\displaystyle 1+8+7+4=20\)

The final answer is \(\displaystyle 202\).

Example Question #883 : Operations

\(\displaystyle 45+99+73=\)

 

Possible Answers:

\(\displaystyle 287\)

\(\displaystyle 129\)

\(\displaystyle 197\)

\(\displaystyle 217\)

Correct answer:

\(\displaystyle 217\)

Explanation:

\(\displaystyle 45+99+73\)

You first must add the ones place: \(\displaystyle 5+9+3=17\).

You leave the 7 and carry the 1 to the tens place,

\(\displaystyle 1+4+9+7=21\)

The final answer is \(\displaystyle 217\).

Example Question #1102 : Numbers And Operations

\(\displaystyle 59+78+41+5=\)

Possible Answers:

\(\displaystyle 178\)

\(\displaystyle 208\)

\(\displaystyle 188\)

\(\displaystyle 183\)

Correct answer:

\(\displaystyle 183\)

Explanation:

The correct answer is \(\displaystyle 183\).

When adding, you have to add the ones place numbers to each other, and the tens place numbers to each other:

\(\displaystyle 59+78+41+5=\)

\(\displaystyle 9+8+1+5=23\) 

carry the \(\displaystyle 2\) and add

\(\displaystyle 2+5+7+4=18\)

The final answer is \(\displaystyle 183\).

Example Question #884 : Operations

Leigh-Anne is going on a shopping spree! She buys a $108 purse, $52 sweater, and $18 scarf. How much money does Leigh-Anne spend in total?

Possible Answers:

\(\displaystyle \$ 187\)

\(\displaystyle \$ 178\)

\(\displaystyle \$ 177\)

\(\displaystyle \$ 199\)

\(\displaystyle \$ 188\)

Correct answer:

\(\displaystyle \$ 178\)

Explanation:

Since Leigh-Anne is spending money over time on various items, we need to add all three values together to find out the total amount of money she spent!

\(\displaystyle \$ 108 + \$ 52 + \$ 18 = \$ 178\)

Example Question #41 : How To Add

Destiney borrowed $25 from Peter, $15 from Blair, and $9 from Scarlet. How much money did Destiney borrow in all?

Possible Answers:

\(\displaystyle \$ 26\)

\(\displaystyle \$ 59\)

\(\displaystyle \$ 64\)

\(\displaystyle \$ 45\)

\(\displaystyle \$ 49\)

Correct answer:

\(\displaystyle \$ 49\)

Explanation:

Since Destiney is gaining money over time (due to her borrowing money from other people), we should add the three numbers together to find out how much money Destiney borrowed in all!

\(\displaystyle \$ 25 + \$ 15 + \$ 9 = \$ 49\)

Example Question #3 : Adding Multi Digit Decimals

\(\displaystyle 33.4 + 22.7 =\)

Possible Answers:

\(\displaystyle 121.2\)

\(\displaystyle 10.7\)

\(\displaystyle 34.8\)

\(\displaystyle 56.1\)

\(\displaystyle 16.3\)

Correct answer:

\(\displaystyle 56.1\)

Explanation:

Add the "whole" parts of the numbers:  \(\displaystyle 33 + 22 = 55\)

Add the "decimal" parts of the numbers: \(\displaystyle 0.4 + 0.7 = 1.1\)

Add both parts together: \(\displaystyle 55 + 1.1 = 56.1\)

 

 

\(\displaystyle 33.4 + 22.7 = 56.1\)

Example Question #42 : How To Add

The Oglevee Family Farm has 12 chickens, 4 pigs, 18 horses, and 2 cows. How many animals does the Oglevee Family Farm have in all?

Possible Answers:

\(\displaystyle 48\)

\(\displaystyle 36\)

\(\displaystyle 44\)

\(\displaystyle 28\)

\(\displaystyle 101\)

Correct answer:

\(\displaystyle 36\)

Explanation:

Since we need to figure out the total number of animals at the Oglevee Family Farm, we need to add the number of chickens, pigs, horses, and cows together.

\(\displaystyle 12 + 4 + 18 + 2 = 36\)

Example Question #43 : How To Add

Arlie is buying Hanukkah gifts for his family. He buys a \(\displaystyle \$24\) scarf for his mother, a \(\displaystyle \$18\) basketball for his brother, and a \(\displaystyle \$33\) tie for his father. How much total money does Arlie spend?

\(\displaystyle \$56\)

\(\displaystyle \$84\)

\(\displaystyle \$101\)

\(\displaystyle \$85\)

Explanation:

We need to add the cost of the three gifts together to find how much money Arlie spent in all.

\(\displaystyle \$24 + \$18 + \$33 = \$75\)
