Answer 1

$1 \ \frac{1}{48} - 1 + \frac{7}{36} \\ = \frac{49}{48 } - 1 + \frac{7}{36} \\ = \frac{(49 \times 3)}{144} - \frac{(1 \times 144)}{144} + \frac{(7 \times 4)}{144} \\ = \frac{147}{144} - \frac{144}{144} + \frac{28}{144} \\ = \frac{147 - 144 + 28}{144} \\ = \frac{3 + 28}{144} \\ = \frac{31}{144}$

Hope this helps you.
