Subtract the sum of minus 3 upon 10 and 5 upon 8 from the sum of 4 upon 15 and 2 upon minus 5

Answer 1

$\sf\underline{Step-by-step \: explanation}$

Question :

$( \frac{ 4}{15} \: + \frac{2}{ - 5}) \: - \: ( \frac{ - 3}{10} \: + \: \frac{5}{ 8} )$

First; let's find out the sum of -3/10 and 5/8

LCM of 8 and 10 = 40

Making the terms like,

$\frac{ - 12}{40} \: + \: \frac{25}{40}$

After Solving...

$\frac{13}{40}$

Step-2 Find out the sum of 4/15 and 2/-5

Remember - Denominator can never have a negative sign. So, the fraction now, will be, -2/5

LCM of 15 and 5 = 15

Making the terms like,

$\frac{4}{15} \: + \: \frac{ - 6}{15}$

After Solving,

$\frac{ - 2}{15}$

Solving further,

$\frac{ - 2}{15} \: - \: \frac{13}{40}$

LCM of 40 and 15 = 120

Converting them to like terms,

$\frac{ - 16}{120} \: - \: \frac{39}{120}$

$\frac{ - 55}{120}$

Cancelling,

$\frac{ - 5}{24}$
