(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) \(\square + \frac{5}{27} = \frac{12}{27} \)

\(\square = \frac{12}{27} - \frac{5}{27} \)

\(\square = \frac{7}{27} \)

- Q.1 Write these fractions appropriately as additions or subtractions:
- Q.2 Solve: (a) \(\frac{1}{18} + \frac{1}{18} \) (b) \(\frac{8}{15} + \frac{3}{15} \) (c) \(\frac{7}{7} - \frac{5}{7} \) (d) \(\frac{1}{22} + \frac{21}{22} \) (e) \(\frac{12}{15} - \frac{7}{15} \) (f) \(\frac{5}{8} + \frac{3}{8} \) (g) 1 – \(\frac{2}{3} \) (1 = \(\frac{3}{3} \) ) (h) \(\frac{1}{4} + \frac{0}{4} \) (i) 3 - \frac{12}{5} \)
- Q.3 Shubham painted \(\frac{2}{3} \) of the wall space in his room. His sister Madhavi helped and painted \(\frac{1}{3} \) of the wall space. How much did they paint together?
