100\times 45=r\times 96
Variable r cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 100r, the least common multiple of r,100.
4500=r\times 96
Multiply 100 and 45 to get 4500.
r\times 96=4500
Swap sides so that all variable terms are on the left hand side.
r=\frac{4500}{96}
Divide both sides by 96.
r=\frac{375}{8}
Reduce the fraction \frac{4500}{96} to lowest terms by extracting and canceling out 12.
