Question

miscellaneous 2/3+(-4/5-5/6)and(2/3-4/5)-5/6 are the two sums equal

Answer 1

2/3 + (-4/5 - 5/6) = 2/3 - 4/5 - 5/6

= 10 - 12 / 15 - 5/6

= -2/15 - 5/6

= -4 - 30 / 30

= -34/30

= -17/15

Now,

(2/3 - 4/5) - 5/6

= 10 - 12 / 15 - 5/6

= -2/15 - 5/6

= -4-30/30

= -34/30

= -17/15

Therefore, 2/3 + (-4/5 -5/6) is equal to (2/3 -4/5) - 5/6
