Find: i) \(\frac{7}{11}\) of 330 ii) \(\frac{5}{9}\) of 108 iii)�

1.	Find: i) \(\frac{7}{11}\) of 330 ii) \(\frac{5}{9}\) of 108 iii) \(\frac{2}{7}\) of 16 iv) \(\frac{1}{7}\) of \(\frac{3}{10}\)
Answer» i) \(\frac{7}{11}\) of 330 = \(\frac{7}{11}\) × 330 = \(\frac{7}{11}\) × 11 × 30 = 7 × 30 = 210 ii) \(\frac{5}{9}\) of 108 = \(\frac{5}{9}\) × 108 = \(\frac{5}{9}\) × 9 × 12 = 5 × 12 = 60 iii) \(\frac{2}{7}\) of 16 = \(\frac{2}{7}\) × 16 = \(\frac{2\times16}{7}\) = \(\frac{32}{7}\) or \(4\frac{4}{7}\) iv) \(\frac{1}{7}\) of \(\frac{3}{10}\) = \(\frac{1}{7}\) × \(\frac{3}{10}\) = \(\frac{1\times3}{7\times10}\) = \(\frac{3}{70}\)

Find: i) \(\frac{7}{11}\) of 330 ii) \(\frac{5}{9}\) of 108 iii) \(\frac{2}{7}\) of 16 iv) \(\frac{1}{7}\) of \(\frac{3}{10}\)

Answer»

i) \(\frac{7}{11}\) of 330

= \(\frac{7}{11}\) × 330

= \(\frac{7}{11}\) × 11 × 30

= 7 × 30 = 210

ii) \(\frac{5}{9}\) of 108

= \(\frac{5}{9}\) × 108

= \(\frac{5}{9}\) × 9 × 12

= 5 × 12 = 60

iii) \(\frac{2}{7}\) of 16

= \(\frac{2}{7}\) × 16

= \(\frac{2\times16}{7}\)

= \(\frac{32}{7}\) or \(4\frac{4}{7}\)

iv) \(\frac{1}{7}\) of \(\frac{3}{10}\)

= \(\frac{1}{7}\) × \(\frac{3}{10}\)

= \(\frac{1\times3}{7\times10}\)

= \(\frac{3}{70}\)
