Given

Yoshi need $1\frac{1}{4}$ cups of blueberries to make 1 batch of muffins

convert mixed fraction to fraction

$\Rightarrow 1\dfrac{1}{4}=\dfrac{5}{4}$

i.e. $\frac{5}{4}$ cups are required for 1 batch of muffins

for $2\frac{1}{2}$ batch or $\frac{5}{2}$ batch it is given by

$\Rightarrow \dfrac{5}{2}\times \dfrac{5}{4}\\\\\Rightarrow \dfrac{25}{8}=3\dfrac{1}{8}\ \text{cups}$
