Question

which expression will give a better estimate of 48.9 ÷ 5?
45 ÷ 5 50 ÷ 5
use the expression you picked to estimate the quotient.
48.9 ÷ 5 is about .

Explanation:

Part 1: Which expression gives a better estimate?

Step1: Compare distances to 48.9

Calculate how far 45 and 50 are from 48.9.
Distance for 45: \( |48.9 - 45| = 3.9 \)
Distance for 50: \( |48.9 - 50| = 1.1 \)

Step2: Determine better estimate

Since 50 is closer to 48.9 (smaller distance), \( 50 \div 5 \) is better.

Step1: Simplify \( 50 \div 5 \)

Divide 50 by 5: \( 50 \div 5 = 10 \)

Since \( 50 \div 5 = 10 \) and 50 is close to 48.9, the estimate is 10.

Answer:

\( 50 \div 5 \)

Part 2: Estimate the quotient using \( 50 \div 5 \)
