Answer 2

Answer:

$\frac{5}{8} + \frac{1}{4} = \frac{5 \times 4 + 1 \times 8}{8 \times 4} = \frac{20 + 8}{32} = \frac{28}{32} = \frac{14}{16 } = \frac{7}{8 } \\ = \frac{7}{8} - \frac{7}{12} = \frac{7 \times 12 - 7 \times 8}{8 \times 12} = \frac{84 - 56}{96} = \frac{28}{96} = \frac{14}{48 } = \frac{7}{24}$

7/24 is the required number
