Question

1. eli wants to find 73 - 59. which shows a correct way to change the numbers using compensation? a 74 - 60 b 72 - 60 c 70 - 60 d 70 - 62

Explanation:

Step1: Recall compensation method

In subtraction, compensation means adjusting both numbers by the same amount so the difference remains the same. If we increase the subtrahend, we should also increase the minuend by the same amount.

Step2: Analyze 59 to 60

We want to change 59 to 60 (increase by 1). So we need to increase 73 by 1 as well.

Step3: Calculate adjusted numbers

73 + 1 = 74, 59 + 1 = 60. So the expression becomes 74 - 60.

Answer:

A. 74 − 60
