Write each rational number as a decimal. If there’s no whole number, make sure to include a zero in the beginning so if your answer is 0.7 make sure to put a zero in the beginning.

First, let's convert the fraction 5/16 into a decimal number, by dividing 5 and 16:
[tex]\frac{5}{16}=0.3125[/tex]Now, let's add the 5 units to the decimal:
[tex]5\frac{5}{16}=5+\frac{5}{16}=5+0.3125=5.3125[/tex]Therefore the answer is 5.3125.
