9x=5\times 4.5
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5x, the least common multiple of 5,x.
9x=22.5
Multiply 5 and 4.5 to get 22.5.
x=\frac{22.5}{9}
Divide both sides by 9.
x=\frac{225}{90}
Expand \frac{22.5}{9} by multiplying both numerator and the denominator by 10.
x=\frac{5}{2}
Reduce the fraction \frac{225}{90} to lowest terms by extracting and canceling out 45.
