Question

(i) 252 is 35% of a certain number, find the number. (ii) If 14% of a number is 315 ; find the number.

Answer 1

Answer:

(i) The number is 720.

(ii) The number is 2100

Step-by-step explanation:

(i) It is given that 35% of an unknown number x is 252, so that gives us the working equation:

x * 0.35 = 252

We then divide 0.35 to both sides of the equation, to cancel out 0.35 on the left side and leaving x.

x = 252/0.35

x = 720

(ii) We do the same process for this problem.

x * 0.14 = 315

x = 315/0.14

x = 2100
