N\times 16=4\times 15
Variable N cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4N, the least common multiple of 4,N.
N\times 16=60
Multiply 4 and 15 to get 60.
N=\frac{60}{16}
Divide both sides by 16.
N=\frac{15}{4}
Reduce the fraction \frac{60}{16} to lowest terms by extracting and canceling out 4.
