Q.4. Fill in the missing fractions. (a) \(\frac{7}{10} - \square = \frac{3}{10} \)
(b)\(\square - \frac{3}{21} = \frac{5}{21} \)
(c) \(\square - \frac{3}{6} = \frac{3}{6} \)
(d) \(\square + \frac{5}{27} = \frac{12}{27} \)


Answer :

(a) \(\frac{7}{10} \square = \frac{3}{10} \)
Or, \( - \square = \frac{3}{10} - \frac{7}{10} \)
Or, \(-\square = - \frac{4}{10} = -\frac{2}{5} \)
Or, \(\square = \frac{2}{5} \)
(b) \(\square - \frac{3}{21} = \frac{5}{21} \)
Or, \(\square = \frac{5}{21} + \frac{3}{21} \)
Or, \(\square = \frac{8}{21} \)
(c) \(\square - \frac{3}{6} = \frac{3}{6} \)
Or, \(\square = \frac{3}{6} + \frac{3}{6} \)
Or, \(\square = \frac{6}{6} = 1 \) (d) \(\square + \frac{5}{27} = \frac{12}{27} \)
\(\square = \frac{12}{27} - \frac{5}{27} \)
\(\square = \frac{7}{27} \)
