Step-by-step explanation:

Earnings = 75

Spendings =

$30\frac{1}{4} + 20 \frac{1}{2} \\ \\ \frac{121}{4} + \frac{41}{2} \\ \\ taking \: \: lcm \\ \\ \frac{121}{4} + \frac{41 \times 2}{2 \times 2} \\ \\ \frac{121}{4} + \frac{82}{4} \\ \\ \frac{121 + 82}{4} \\ \\ \frac{203}{4}$

Savings = Earnings - Spending

$Savings =75 - \frac{203}{4} \\ \\ taking \: \: lcm \\ \\ \frac{75 \times 4}{1 \times 4} - \frac{203}{4} \\ \\ \frac{300}{4} - \frac{203}{4} \\ \\ \frac{300 - 203}{4} \\ \\ Savings = \frac{97}{4}$
