Question

if 1/4 of a number is 1 more than 1/5 of the same number, find the number.

Answer 1

You will have to multiply 1 by 4, then divide that number by 5

Answer 2

Use x for "a number"

Then 1/4 of a number means (1/4)x

Also, 1/5 of the same number is (1/5)x
1 more than 1/5 of a number is (1/5)x + 1

Set
(1/4)x = (1/5)x+ 1
and solve the equation for x.
