Question

80% of a number is x. What is 100% of the number.

Answer 1

Answer:

We have, 80% × x = 100

or,

80/100×1 x = 100

Multiplying both sides by 100 and dividing both sides by 80,

we have x = 100 × 100/80

x = 125

If you are using a calculator, simply enter 100×100÷80, which will give you the answer.
