**Selected Response**

Question 1.

What is -7\(\frac{5}{12}\) written as a decimal?

A. -7.25

B. -7.333.

C. -7.41666…

D. -7.512

Answer:

C. -7.41666…

First, write \(\frac{5}{12}\) as a decimal.

Then, add 7 to the result.

7 + \(0.41 \overline{6}\) = \(7.41 \overline{6}\)

Now, since the starting number was negative, this one has to be negative too.

-7\(\frac{5}{12}\) = –\(7.41 \overline{6}\)

Question 2.

Which set or sets does the number -9\(\frac{1}{2}\) belong to?

A. Integers only

B. Rational numbers only

C. Integers and rational numbers only.

D. Whole numbers, integers, and rational numbers

Answer:

B. Rational numbers only

-9\(\frac{1}{2}\) is a mixed fraction. Thus, it is onLy a rational number.

Question 3.

Renee ate \(\frac{1}{4}\) of a pizza, and Sumi ate of the same pizza. How much of the pizza did they eat in all?

A. \(\frac{1}{7}\) of the pizza

B. \(\frac{2}{7}\) of the pizza

C. \(\frac{5}{12}\) of the pizza

D. \(\frac{7}{12}\) of the pizza

Answer:

D. \(\frac{7}{12}\) of the pizza

We have to add how much Renee ate, and how much Sumi ate.

\(\frac{1}{4}\) + \(\frac{1}{3}\) = \(\frac{3+4}{12}\)

= \(\frac{7}{12}\)

Renee and Sumi ate \(\frac{7}{12}\) of the pizza

Question 4.

Kareem had $25 in his bank account on Monday. The table shows his account activity for the next four days. What was the balance in Kareem’s account on Friday?

A. $59.23

B. -$9.23

C. $9.23

D. -$59.23

Answer:

A. $59.23

Use positive numbers to represent deposit and negative numbers to represent withdrawal. Then, add it up to account’s balance before any deposits or withdrawals, 25.

25 + (-13.50) + 85.10 + (-55.32) + 17.95 = 25 + 85.10 + 17.95 – 13.50 – 55.32

= – 110.10 + 17.95 – 13.50 – 55.32

= 128.05 – 13.50 – 55.32

= 114.55 – 55.32

= 59.2:3

The balance in Kareem’s account. on Friday was $59.23.

C. 2\(\frac{3}{5}\) bags

D. 2\(\frac{5}{9}\) bags

Answer:

C. 2\(\frac{3}{5}\) bags

Start with dividing 23\(\frac{2}{5}\) by 9:

23\(\frac{2}{5}\) ÷ 9

Write mixed fraction as proper fraction:

\(\frac{117}{5}\) ÷ 9

Write using multiplication:

\(\frac{117}{5}\) × \(\frac{1}{9}\) = \(\frac{13}{5}\)

= 2\(\frac{3}{5}\)

Each friend gets 2\(\frac{3}{5}\) bags
