​

Answer 1

Answer:

$\frac{267}{112}$

Step-by-step explanation:

$\frac{1}{ 8} + \frac{5}{12} + \frac{2}{7} + \frac{7}{12} + \frac{9}{7} - \frac{5}{16}$

$LCM \: = 2 \times 2 \times 2 \times 3 \times 7 \times 2 = 336$

$( \frac{1 \times42 }{8 \times 42} ) + ( \frac{5 \times28 }{12 \times 28} ) + ( \frac{2 \times48 }{ 7\times48 } ) + ( \frac{7 \times 28}{12 \times28 } ) + ( \frac{9 \times 48}{7 \times 48} ) - ( \frac{5 \times 21}{16 \times 21} )$

$\frac{42}{336} + \frac{140}{336} + \frac{96}{336} + \frac{196}{336} + \frac{432}{336} - \frac{105}{336}$

$\frac{42 + 140 + 96 + 196 + 432 - 105}{336}$

$\frac{801}{336}$

divide it by 3✌️

$\frac{267}{112}$
