Question

Grace uses a different way to divide 2.16 by 0.25 .She divides both the divisor and dividend by 0.01 to make an equivalent problem with a whole number divisor is her work correct ? Explain

Answer 1

8.64. Her work is correct

Explanation:

Given the expression to divide 2.16 by 0.25

Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;

2.16/0.25 = (2.16/0.01)÷(0.25/0.01)

(2.16/0.01)÷(0.25/0.01) = 216/25

216/25 = 8.64

Hence her value is 8.64 making her work correct
