120 ÷ 3 = \square, so 124 ÷ 3 is about ? ^

Explanation:

Step1: Calculate 120 ÷ 3

We know that 3 times 40 is 120, so $120\div3 = 40$.

Step2: Estimate 124 ÷ 3

Since 124 is close to 120, and we found that 120 ÷ 3 = 40, so 124 ÷ 3 is about 40 (because 124 is just a bit more than 120, but for a reasonable estimate, we use the result from 120 ÷ 3).

First blank: 40; Second blank: 40
