What approximate value will come in place of question mark (?) in the given questions ? (You are not expected to calculate the exact value.)

Question 45

1/5+2/15+?+1/6= $$1\frac{1}{6}$$

Solution

Expression : 1/5+2/15+?+1/6= $$1\frac{1}{6}$$

=> $$\frac{1}{5} + \frac{2}{15} + x + \frac{1}{6} = \frac{7}{6}$$

=> $$\frac{3}{15} + \frac{2}{15} + x = \frac{7}{6} - \frac{1}{6}$$

=> $$\frac{5}{15} + x = \frac{6}{6}$$

=> $$\frac{1}{3} + x = 1$$

=> $$x = 1 - \frac{1}{3} = \frac{2}{3}$$
