Answer 1

Answer:

Hey man I am there to help you.

-4/5 ×5/7×(-8/9)+8/9×4/7 this is the question.

The answer is first we should multiply 5/7 with (-8/9).

-4/5×-40/63+8/9×4/7

-4/5×-40/63+32/63.

160/315+32/63.

160+160/315=320/315.

64/63 is the answer of "a".

b) -3/2×-6/5+2/3+5/6÷7/6 is the question.

First divide,

-3/2×-6/5+2/3+5/7.

Now multiply.

18/10+2/3+5/7.

2/3+5/7=14/21+15/21=29/21.

18/10+29/21=378/210+290/210=668/210

I hope it may be helpful.
