Answer 1

Step-by-step explanation:

1) a+(b+c) = (a+b) +c

put the values in given equation,

2/3+(4/5+5/6) = (2/3+4/5) +5/ 6 make the devisor equal (of bracket) 2/3+(4×6/5×6+5×5/6×5) = (2×5/3×5+4×3+5×3)

+5/6

2/3+(24/30+25/30) = (10/15+12/15)+5/ 6 again make the devisor equal,

2×10/3×10+49×1/30×1 = 22×2/15×2+5×5/6×5

20/30+49/30 = 44/30+25/30

finally we get the answer,

69/30 = 69/30

2nd Q. is also like this

2) a×(b×c) = (a×b)×c

put the values,

2/3×(4/5×5/6) = (2/3×4/5) ×5/6

Solve this answer by multiplication

you will get the answer

I hope you will solve this,

ALL THE BEST
