Simplify:
$\frac{5}{6} - \frac{4}{9} + \frac{2}{3}$

Open in App

Solution

We have:

$\frac{5}{6} - \frac{4}{9} + \frac{2}{3} L . C . M . of 3, 6 and 9 = (2 \times 3 \times 3) = 18 = \frac{(15 - 8 + 12)}{18} \{[18 \div 6 = 3, 3 \times 5 = 15], [18 \div 9 = 2, 2 \times 4 = 8] and [18 \div 3 = 6, 6 \times 2 = 12]\} = \frac{(27 - 8)}{18} = \frac{19}{18} = 1 \frac{1}{18}$
