The whole

3/4 ÷ 25%
= 3/4 ÷ 25/100
= 3/4 x 100/25
= 300/100
= 3

The easiest way to look at this is to either change 3/4 to a decimal (which is 0.75) or change 25% to a fraction (which is 25/100). Using the language of mathematics, write in symbols what you have:
3/4 is (= ) 25/100 of (times) what (? or x or some other variable)
Then you have 3/4 = 25/100 * x
To find x, divide by the coefficient (number) times x on both sides
3/4 div 25/100 = 25/100 div 25/100 times x
To divide, invert and multiply
3/4 * 100/25 = x
3/4 * 4/1 = x
3 = x which is the solution to your problem.

let 25% of x = 3/4
⇒ 25×x/100 = 3/4
⇒ x = 3×100/(4×25)
⇒ x = 3

Rewrite the expression as

3/4 = 25% * N

Rewrite 25% as a fraction, which is 1/4

3/4 = 1/4 * N

Multiply both sides by 4
N = 3, that's your final answer.

2

because .75 x 4= 2

3/4 = 1/4x
4/1(3/4) = 4/1(1/4x)
3 = x
