randRange(1, 99) randRange(1, 2) pow(10, PLACES) roundTo(3, NUMERATOR / DENOMINATOR)

Express the fraction as a decimal.

\large{\dfrac{NUMERATOR}{DENOMINATOR}}

SOLUTION

This fraction represents the result of dividing NUMERATOR by DENOMINATOR.

Dividing by DENOMINATOR is the same as moving the decimal one position to the left.

Dividing by DENOMINATOR is the same as moving the decimal two positions to the left.
