x\times \frac{\frac{5}{4}}{\frac{5}{8}}=24
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times \frac{5}{4}\times \frac{8}{5}=24
Divide \frac{5}{4} by \frac{5}{8} by multiplying \frac{5}{4} by the reciprocal of \frac{5}{8}.
x\times \frac{5\times 8}{4\times 5}=24
Multiply \frac{5}{4} times \frac{8}{5} by multiplying numerator times numerator and denominator times denominator.
x\times \frac{8}{4}=24
Cancel out 5 in both numerator and denominator.
x\times 2=24
Divide 8 by 4 to get 2.
x=\frac{24}{2}
Divide both sides by 2.
x=12
Divide 24 by 2 to get 12.
