Question

19. Divide 36 into two parts in such a way that 1/5 of one part is equal to 1/7 of the other

Answer 1

May be you wanna say there are two parts of 36

let one part be x, then the other will be (36-x)

according to the question,

x/5 = 36-x/7

7x= 5(36) -5x
12x = 180
x= 15
thus, the other part will be
36-x
36-15=21
