35 is 20% of
what number?

175

Step-by-step explanation:

Let N be the wanted number.

We are told that 20% of N = 35

Then:

N·20/100 = 35

We know how to clear N:

N = 100·35/20

N= 3500/20 = 175

Answer = 175

Step-by-step explanation:

Let the number be A

A × 20 /100 = 35

Multiply

20A /100 = 35

Cross multiply

20A = 35 × 100

20A = 3500

Divide both sides by 20

20A /20 = 3500 / 20

A = 175
