[tex]\Rightarrow 1\dfrac{1}{4}=\dfrac{5}{4}[/tex]
i.e. [tex]\frac{5}{4}[/tex] cups are required for 1 batch of muffins
for [tex]2\frac{1}{2}[/tex] batch or [tex]\frac{5}{2}[/tex] batch it is given by
[tex]\Rightarrow \dfrac{5}{2}\times \dfrac{5}{4}\\\\\Rightarrow \dfrac{25}{8}=3\dfrac{1}{8}\ \text{cups}[/tex]
