Question

Three students claim that solving the division equation is like solving a multiplication equation.

The equations that each student came up with are shown in the table.

Answer 1

1. Roy

2. k = 15

Explanation:

equation 5 ÷ 1/3 = k

Jill k x 1/3 = 5 √

Roy k x 5 = 1/3 x

Ted 5 = 1/3 x k √

solving the equation

k = (5 x 3) / 1

k = 15
