The fraction is 4x/5x where x is a number. You have that 4x + 5x=36, so solve for x, then you have what 4*x is and 5*x.

The answer for "x" is 4

4x+5x=36

9x=36

divide both sides by 9

x=4

check: 4*4+5*4=36

16+20=36

36=36

x + y = 36

x/y = .80

.80y + y = 36

1.8y = 36/y = 20

x = 16

4x+5x=36
