Question

if 1/2 of a number is added to 3/5 of the number we get 36 less than 7/8 of that number. Find the number.​

Answer 1

Answer:

the number is 36

5/6 * x - 3/4 * x = 3

10/12 * x - 9/12 * x = 3

1/12x = 3

x = 3*12 = 36

check:

5/6*36 = 30

3/4*36 = 27

30 - 27 = 3

Answer 2

Let x be that number

According to the question ,

1/2 of x + 3/5 of x =7/8 of x - 36

x/2 + 3x/5 = 7x/8 - 36

5x+6x/10=7x-288/8

11x/10 = 7x-288/8

11x × 8 = (7x-288)× 10

88x = 70x -2880

18x= -2880

x= -160 ..

thus, the number is

-160
