Question

$\text{Jack}$ saves $$1.50$ per day from his parents allowance. $\text{Jones}$, his friend, borrows $$0.7$ from him daily. Find out how much money Jack saves per day after lending to Jones.

• A. $\frac{5}{4}$
• B. $\frac{4}{5}$
• C. $\frac{7}{10}$
• D. $\frac{7}{8}$

Answer 1

The correct option is B $\frac{4}{5}$

Daily allowance $=1.5$
Daily money borrowed $=0.7$
Remaining money (in $)
$=1.5-0.7$
$=0.8$
$\therefore$ Jack saves $0.8 per day from his daily allowance.

To report the correct answer, convert the decimal $0.8$ into fraction.
So, Jack saves per day
$=0.8=\frac{0.8}{1}$
$=\frac{0.8}{1}\times \frac{10}{10}$
$=\frac{8}{10}$
$=\frac{4}{5}$
Answer: $\therefore$ Jack saves $$\frac{4}{5}$ per day from his daily allowance.
