To find out how much it rained in April, you subtract the amount it rained less in April from the amount it rained in March.
March rainfall: 5 inches
Rainfall reduction in April: 0.753 inches
So, the rainfall in April is calculated as follows:
\[ \text{April Rainfall} = \text{March Rainfall} - \text{Rainfall Reduction} \] \[ \text{April Rainfall} = 5 \text{ inches} - 0.753 \text{ inches} \] \[ \text{April Rainfall} = 4.247 \text{ inches} \]
Therefore, it rained 4.247 inches in April.
