A fraction is equivelant to 4/5. The sum of the numerator and the denominator of the fractionis 36. What is the fraction?
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
