$chapter \: rational \: number$
​

Answer 1

Step-by-step explanation:

add

2/5× 5/9 + (-6) /15

the five will candel each other we get

2/9-6/15

10-18/45

= -8/45

subtract

-3/14-5/8

-12-35/56

= -57/56

Answer 2

2/5 + (-5/9) + (-6/15)

=18/45-25/45-18/45(taking lcm)

= -25/45 = -0.56

also,

-3/14 - 5/8

= -12/56-35/56(taking lcm)

=-47/56 = -0.84
