Question

1. which expressions have an estimated quotient of 25? choose all ans a. 74.5 ÷ 2.9 b. 99.65 ÷ 4.02 c. 150.49 ÷ 5.1 d. 199.73 ÷ 5.59 e. 201.13 ÷ 7.98

Explanation:

Step1: Estimate expression A

Round $74.5\approx75$, $2.9\approx3$. $\frac{75}{3}=25$

Step2: Estimate expression B

Round $99.65\approx100$, $4.02\approx4$. $\frac{100}{4}=25$

Step3: Estimate expression C

Round $150.49\approx150$, $5.1\approx5$. $\frac{150}{5}=30$

Step4: Estimate expression D

Round $199.73\approx200$, $5.59\approx6$. $\frac{200}{6}\approx33.33$

Step5: Estimate expression E

Round $201.13\approx200$, $7.98\approx8$. $\frac{200}{8}=25$

Answer:

A. $74.5 \div 2.9$, B. $99.65 \div 4.02$, E. $201.13 \div 7.98$
