To determine a fraction with an indicated denominator you firstly divide the indicated denominator by the denominator of the fraction.
Example: $\frac{2}{5} = \frac{}{ 20}$.
First step: $20 \div 5 = 4$.
Secondly, you multiply the nominator with the resulting number to get the new numerator
Second step: $ 2 \cdot 4 = 8$.
And the result is $\frac{8}{20}$.
