Question

simplify using suitable identity.
7/20*6/17+11/17*7/20

Answer 1

Step-by-step explanation:

$= \frac{7}{20} \times \frac{6}{17} + \frac{11}{17} \times \frac{7}{20} \\ = \frac{7}{20} ( \frac{6}{17 } + \frac{11}{17}) \\ = \frac{7}{20} ( \frac{6 + 11}{17} ) \\ = \frac{7}{20} ( \frac{17}{17} ) \\ = \frac{7}{20}$
