Answer 1

Answer: $1\dfrac{3}{8}\ \text{inch}$

Step-by-step explanation:

Given

Rainfall in September is $\frac{7}{8}$ inch

Rainfall in October is $2\frac{1}{4}$ inch

Convert mixed fraction into fraction

$\Rightarrow 2\dfrac{1}{4}=\dfrac{9}{4}\ \text{inch}$

Difference between the two gives that how much more rain fall in October compared to September

$\Rightarrow \dfrac{9}{4}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{18-7}{8}\\\\\Rightarrow \dfrac{11}{8}\ \text{inch or}\\\\\Rightarrow 1\dfrac{3}{8}\ \text{inch}$
