Hello dear!

Here is your answer.

This is the calculation of fraction

-7/4 + 0 + -9/5 + 19/10 + 11/14

We know that when any number is added with '0', the result will be the same number which is added with '0'.

=> ( -7/4 ) + ( -9/5 ) + ( 19/10 ) + ( 11/14 )

Firstly make two pairs,

1. ( -7/4 ) + ( -9/5 )

By the help of butterfly method, calculate it.

The rules of butterfly method with picture given at the top.

=> ( -35 ) + ( -36 ) / 20

=> ( -35 + 36) / 20

=> 1/20 ________(1 pair)

Now,

2. ( 19/10 ) + ( 11/14 )

By the help of butterfly method, calculate it.

The rules of butterfly method with picture given at the top.

=> ( 266 + 110 ) / 140

=> 376 / 140

=> 94 / 35 _______(2 pair)

Now, add (1 pair) and (2 pair):

By the help of butterfly method, calculate it.

The rules of butterfly method with picture given at the top.

=> 1/20 + 94 / 35

=> 35 + 1880 / 700

=> 1,915 / 700 = 383 / 140

=> 383 / 140

Answer is 383 / 140 .
