Answer 2

Hey Mate!!

i) -5/14 + (-7/-10)

=-5/14 + 7/10

Find LCM to make the denominators equal.

LCM of 14 and 10 is 70

So, (-5/14 × 5/5) + (7/10 × 7/7)

= -25/70 + 49/70

=24/70.

ii) 32/6 ÷ ( 9/5-3/4)

First, for 9/5 and 3/4 , Find LCM

LCM of 5 and 4 is 20

So, (9/5×4/4) - (3/4×5/5)

=36/20 - 15/20

=21/20

Now, 32/6 ÷ 21/20

It can also be return as 32/6 × 20/21

After simplification process,

= 32/3 × 10/21

= 10.6666667 × 0.476190476

= 5.07936508

Hope this helps you!!
