Question

if we subtract 14 2/7% of a number from itself then we get 7800 find the number​

Answer 1

Step-by-step explanation:

let x be the number

therefore,

14 2/7 % = 100/7 %

and from question we have

x-(100/7)%of x = 7800

x- (100/7÷100 × x = 7800

x-( 100/7 × 1/100)×x = 7800

x-(1/7)x = 7800

7x-1x = 7800

7

6x = 7800× 7

x = 7800×7 = 1300×7 = 9100
