Multiply 25 and 5/2

Answer 1

To find the number of students who walk to school (which is 2/5 of 25), the correct method is:

Divide 25 by 5 and then multiply the quotient by 2.

Here's the reasoning:

1. We first divide 25 by 5 to find out what 1/5 of 25 is.

   • 25 ÷ 5 = 5 (this is 1/5 of the total)

2. Then, we multiply that result by 2 to find 2/5 of 25.

   • 5 × 2 = 10

So, 10 students walk to school.
