Question

divide 36 into two parts in such a way that 1 by 5 of one part is equal to 1 by 7 of the other

Answer 1

Let the smaller number be x.
Greater number=36-x
1/5x=1/7(36-x)
1/5x=36/7-1/7x
1/5x+1/7x=36/7
12x/35=36/7
x=36/7×35/12
x=15
36-x=36-15=21

Answer 2

Answer:

one number is 15 and another is 21

Step-by-step explanation:

x/5 = 36-x/7

x * 7 = 36 - x * 5

7x = 180 - 5x

7x + 5x = 180

12x = 180

x = 180 / 12

x = 15

36 - x = 36 - 15 = 21

so 15 and 21
