Question

simplify it please
answer should be 69/40​

Answer 1

Step-by-step explanation:

$first \: remove \: negative \: sign \: \\ from \: denomintor \: and \: put \: \\ \ them \: in \: numerator$

Now, the question be like :-

$\frac{3}{5} + ( \frac{ - 1}{2} + \frac{ - 7}{8}) + ( \frac{ - 3}{2} )$

Now, LCM of 5, 2 8 and 2= 40

$\frac{3}{5} \times 8 = \frac{24}{40 }$

$\frac{ - 1}{2} \times 20 = \frac{ - 20}{40}$

$\frac{ - 7}{8} \times 5 = \frac{ - 35}{40}$

$\frac{ - 3}{2} \times 20 = \frac{ - 60}{40}$

Now,

$\frac{24}{40} + \frac{ - 20}{40} + \frac{ - 35}{40} + \frac{ - 60}{40 } = \frac{ - 91}{40}$

$\frac{ - 91}{40} \: is \: the \: answer \:$
