Answer 2

Answer:

The difference is found to be $\frac{-103}{70}$

Step-by-step explanation:

To find the difference between the following fractions we have to first do the LCM of the given denominators and then change the given fractions into the like terms, henceforth finding the sum. Therefore we have,

$\frac{-9}{10} + \frac{4}{-7}$

We have the LCM of the two numbers, 10 and 7 to be 70

= $\frac{-9*7}{70} + ( \frac{-4*10}{70} )$

= $\frac{-63}{70} - \frac{40}{70}$

= $\frac{-63 - 40}{70}$

= $\frac{- 103}{70}$

Therefore the value of the above sum is $\frac{-103}{70}$
