Explanation: \(\frac{3}{5}\) × 8 = \(\frac{24}{5}\) The mixed fraction of \(\frac{24}{5}\) is 4 \(\frac{4}{5}\) \(\frac{3}{5}\) × 8 = 4 \(\frac{4}{5}\)

Question 6. \(\frac{1}{4}\) × 10 = _____ \(\frac{□}{□}\)

Explanation: \(\frac{1}{4}\) × 10 2 divides 10 five times. \(\frac{1}{2}\) × 5 = \(\frac{5}{2}\) The mixed fraction of \(\frac{5}{2}\) is 2 \(\frac{1}{2}\) \(\frac{1}{4}\) × 10 = 2 \(\frac{1}{2}\)

Question 7. \(\frac{7}{5}\) × 15 = _____

\(\frac{7}{5}\) × 15 5 divides 15 three times. \(\frac{7}{5}\) × 15 = 7 × 3 = 21 \(\frac{7}{5}\) × 15 = 21

Question 8. \(\frac{5}{6}\) × \(\frac{2}{3}\) = \(\frac{□}{□}\)

Answer: \(\frac{5}{9}\)

Explanation: \(\frac{5}{6}\) × \(\frac{2}{3}\) = \(\frac{10}{18}\) \(\frac{10}{18}\) = \(\frac{5}{9}\) Thus \(\frac{5}{6}\) × \(\frac{2}{3}\) = \(\frac{5}{9}\)

Question 9. \(\frac{1}{5}\) × \(\frac{5}{7}\) = \(\frac{□}{□}\)

Answer: \(\frac{1}{7}\)

Explanation: \(\frac{1}{5}\) × \(\frac{5}{7}\) 5 in the numerator and 5 in the denominator gets canceled. = \(\frac{1}{7}\) Thus \(\frac{1}{5}\) × \(\frac{5}{7}\) = \(\frac{1}{7}\)

Question 10. \(\frac{3}{8}\) × \(\frac{1}{6}\) = \(\frac{□}{□}\)

Answer: \(\frac{1}{16}\)

Explanation: \(\frac{3}{8}\) × \(\frac{1}{6}\) 3 divides 6 two times \(\frac{3}{8}\) × \(\frac{1}{6}\) = \(\frac{1}{8}\) × \(\frac{1}{2}\) Multiply the denominators. = \(\frac{1}{16}\) Thus \(\frac{3}{8}\) × \(\frac{1}{6}\) = \(\frac{1}{16}\)

Question 11. \(\frac{7}{8}\) × \(\frac{6}{6}\) will be __________ \(\frac{7}{8}\)

Explanation: \(\frac{7}{8}\) × \(\frac{6}{6}\) \(\frac{6}{6}\) = 1 \(\frac{7}{8}\) × 1 = \(\frac{7}{8}\) \(\frac{7}{8}\) = \(\frac{7}{8}\) Thus \(\frac{7}{8}\) × \(\frac{6}{6}\) will be equal to \(\frac{7}{8}\)

Question 12. \(\frac{1}{2}\) × \(\frac{8}{9}\) will be __________ \(\frac{8}{9}\)

Explanation: \(\frac{1}{2}\) × \(\frac{8}{9}\) Multiply the numerators and denominators \(\frac{1}{2}\) × \(\frac{8}{9}\) = \(\frac{4}{9}\) \(\frac{4}{9}\) is less than \(\frac{8}{9}\) So, \(\frac{1}{2}\) × \(\frac{8}{9}\) will be less than \(\frac{8}{9}\)

Explanation: Compared to all the fractions \(\frac{5}{8}\) is smaller. So, Rachel would reduce the size of her picture to \(\frac{5}{8}\) So, the correct answer is option A.

Question 15. Marteen wants to paint \(\frac{2}{3}\) of her room today. She wants to paint \(\frac{1}{4}\) of that before lunch. How much of her room will she paint today before lunch? Options: a. \(\frac{1}{12}\) b. \(\frac{1}{6}\) c. 1 \(\frac{5}{12}\) d. \(\frac{11}{12}\)

Answer: \(\frac{1}{6}\)

Explanation: Marteen wants to paint \(\frac{2}{3}\) of her room today. She wants to paint \(\frac{1}{4}\) of that before lunch. \(\frac{2}{3}\) × \(\frac{1}{4}\) = \(\frac{1}{6}\) So, the answer is option B.

Question 16. Gia’s bus route to school is 5 \(\frac{1}{2}\) miles. The bus route home is 1 \(\frac{3}{5}\) times as long. How long is Gia’s bus route home? Options: a. 5 \(\frac{3}{10}\) miles b. 8 miles c. 8 \(\frac{4}{5}\) miles d. 17 \(\frac{3}{5}\) miles

Answer: 8 \(\frac{4}{5}\) miles

Explanation: Gia’s bus route to school is 5 \(\frac{1}{2}\) miles. The bus route home is 1 \(\frac{3}{5}\) times as long. 5 \(\frac{1}{2}\) × 1 \(\frac{3}{5}\) Convert the mixed fractions to improper fractions. \(\frac{11}{2}\) × \(\frac{8}{5}\) = \(\frac{88}{10}\) = \(\frac{44}{5}\) The mixed fraction of \(\frac{44}{5}\) is 8 \(\frac{4}{5}\) miles Therefore the answer is option C.

Go Math Grade 5 Chapter 7 Mid Chapter Checkpoint Question 17. Carl’s dog weighs 2 \(\frac{1}{3}\) times what Judy’s dog weighs. If Judy’s dog weighs 35 \(\frac{1}{2}\) pounds, how much does Carl’s dog weigh? Options: a. 88 \(\frac{3}{4}\) pounds b. 82 \(\frac{5}{6}\) pounds c. 81 \(\frac{2}{3}\) pounds d. 71 pounds

Answer: 82 \(\frac{5}{6}\) pounds

Explanation: Carl’s dog weighs 2 \(\frac{1}{3}\) times what Judy’s dog weighs. To find the weigh of Carl’s dog we need to multiply the fractions 2 \(\frac{1}{3}\) and 35 \(\frac{1}{2}\) \(\frac{7}{3}\) × \(\frac{71}{2}\) = \(\frac{497}{6}\) The mixed fraction of \(\frac{497}{6}\) is 82 \(\frac{5}{6}\) pounds. Thus the correct answer is option B.
