Step-by-step explanation:
It is given that,
In March, the precipitation was 4 3/4 inches less than average and for April, the precipitation was 1 1/2 inches less than average.
We need to find how many inches below average was the precipitation for both March and April.
To find it add 4 3/4 inches and 1 1/2 inches. So,
[tex]4\dfrac{3}{4}+1\dfrac{1}{2}\\\\=\dfrac{19}{4}+\dfrac{3}{2}\\\\=\dfrac{19+6}{4}\\\\=\dfrac{25}{4}\\\\=6\dfrac{1}{4}\ \text{inches}[/tex]
So, for both March and April, the precipitation was [tex]6\dfrac{1}{4}\ \text{inches}[/tex] less than average.
