Q. 4. Fill in the boxes:
(a) \(\square - \frac{5}{8} = \frac{1}{4} \)
(b) \(\square - \frac{1}{5} = \frac{1}{2} \)
(c) \(\frac{1}{2} - \square = \frac{1}{6} \)

(a) \(\square - \frac{5}{8} = \frac{1}{4} \)
Or, \(\square = \frac{1}{4} + \frac{5}{8} \)
= \( \frac{1×2}{4×2} + \frac{5}{8} \)
= \( \frac{2}{8} + \frac{5}{8} \) = \(\frac{7}{8}
(b) \(\square - \frac{1}{5} = \frac{1}{2} \)
Or, \(\square = \frac{1}{2} + \frac{1}{5} \)
= \( \frac{1×5}{2×5} + \frac{1×2}{5×2} \)
= \( \frac{5}{10} + \frac{2}{10} \) = \(\frac{7}{10} \)
(C) \(\frac{1}{2} - \square = \frac{1}{6} \)
Or, \(\frac{1}{2} - \frac{1}{6} = \square \)
Or, \(\square = \frac{1×3}{2×3} - \frac{1}{6} \)
Or, \(\square = \frac{3}{6} - \frac{1}{6} \)
Or, \(\square = \frac{2}{6} \) = \(\frac{1}{3} \)
