Question

Caroline was thinking of a number. Caroline divides by 8, then adds 9 to get an answer of 12. What was the original number?

Answer 1

Answer:

24

Step-by-step explanation:

Let Caroline's thinking number be x

and number formed after division be y

so,

x ÷ 8 = y

y + 9 = 12

12 - 9 = 3

y = 3

therefore,

x ÷ 8 = 3

8 × 3 = 24

x = 24

Therefore, the number thought by Caroline was 24.
