Question

Plz help I cannot understand

Answer 1

just equilize the denominator

1)

-3/5+2=-3/5+10/5=8/5

2)

in question no.2 sub question 3 convert it into proper fraction by multiplying 3*-2+1 and 5*4+3

then the proper fraction would be -5/3and23/5

then equilize the denominator by multiplying-5/3with5/5 and 23/5 with 3/3 you will get -25/15 and 69/15 denominator are same so you can add it and answer will be 44/15 check it

similarly do all sums just equilize the denominators of all sum
