Question

addition of 2/3+5/9+7/36+1/2​

Answer 1

Answer:

$= \frac{2}{3} + \frac{5}{9} + \frac{7}{36} + \frac{1}{2} \\ = ( \frac{2}{3} + \frac{5}{9} ) + (\frac{7}{36} + \frac{1}{2}) \\ = ( \frac{2 \times 3}{3 \times 3} + \frac{5}{9} ) + ( \frac{7}{36} + \frac{1 \times 18}{2 \times 18} )\\ = (\frac{6 + 5}{9} ) + ( \frac{7 + 18}{36} )\\ = ( \frac{11}{9} ) + (\frac{25}{36} ) \\ =( \frac{11 \times 4}{9 \times 4}) + ( \frac{25}{36} ) \\ = \frac{44 + 25}{36} \\ = \frac{69}{36} \\ = \frac{69 \div 3}{36 \div 3} \\ = \frac{23}{13} \\ = 1 \frac{11}{12}$
