Question

simplify (5/6*3/11)(9/12*4/3)+(5/13*6/15)​

Answer 1

Answer:

We have,

$( \frac{5}{6} \times \frac{3}{11} )( \frac{9}{12} \times \frac{4}{3} ) + ( \frac{5}{13} \times \frac{6}{15} )$

$= ( \frac{5}{2} \times \frac{1}{11} ) + ( \frac{1}{13} \times \frac{6}{3} )$

$= \frac{5}{22}+ \frac{6}{39}$

$= \frac{(5 \times 39)+(6 \times 22) }{858}$

$= \frac{195+132}{858}$

$= \frac{327}{858}$

$= \frac{109}{286}$
