Question 18.

Eight students share 5 blocks of modeling clay equally. What fraction of one block of modeling clay does each student get?

Options:

a. \(\frac{1}{40}\)

b. \(\frac{1}{8}\)

c. \(\frac{5}{8}\)

d. 1 \(\frac{3}{5}\)

Answer: 1 \(\frac{3}{5}\)

Explanation:

Eight students share 5 blocks of modeling clay equally.

Divide number of students by the number of blocks.

8 ÷ 5 = \(\frac{8}{5}\)

Convert the fraction to the mixed fraction.

\(\frac{8}{5}\) = 1 \(\frac{3}{5}\)

So, the correct answer is option D.

Question 19.

The diagram below represents which division problem?

Options:

a. 5 ÷ \(\frac{1}{3}\)

b. \(\frac{1}{3}\) ÷ 5

c. 5 ÷ \(\frac{1}{4}\)

d. \(\frac{1}{4}\) ÷ 5

Answer: 5 ÷ \(\frac{1}{3}\)

Explanation:

The figure above shows that there are 5 rectangles. Each rectangle is divided into three parts.

So, the fraction is one third.

Divide number of blocks by the number of thirds.

5 ÷ \(\frac{1}{3}\)

Thus the correct answer is option A.
