Question

8) A number is divided by 3, and then 4 is added to the quotient, The result is 8. Find the number.

Answer 1

Solving the problem by working backward.

For Question number 8:

The final number is given as 8 (which is the result of all the operations)

Working backwards, Firstly we need to undo the addition of 4 by subtracting 4 from the result.

`8-4\text{ = 4}`

secondly, we will undo the division by 3, by multiplying the result above by 3.

`4*3\text{ = 12}`

Then we have our answer.

The number is 12
