Question

solve the following:-
(1).7/5*(-7/5)+3/9*9/5+7/9
(2).-3/4*(-4/-3)+6/5*(-5/6)+3/9
(3).9/5+7/6+3/5+(-1)​

Answer 1

Step-by-step explanation:

1. 7/5×(-7/5)+3/9×9/5+7/9

=-49/25+27/45+7/9

= -441+135+175/225

=-441+310/225

=-131/225

2. -3/4×(-4/-3)+6/5×(-5/6)+3/9

=12/-12+-30/30+3/9

=180/-180+-180/180+60/180

=60/180=1/3

3. 9/5+7/6+3/5+(-1)

=54+35+18/30+(-1)

=107/30+(-1)

=3 17/30+(-1)=2 17/30
