Question

verify (-2/3 + 3/5 ) + - 5/6 = - 2/3 (3/5 + - 5/6​

Answer 1

Step-by-step explanation:

By associative property,

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

Hence,

(-2/3+3/5)+ -5/6= -2/3+(3/5+ -5/6)= -27/30= -9/5= -1 4/5

Answer 2

Answer:

They are not equal.

Step-by-step explanation:

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

->  (-10+9/15 ) + (-5/6) = -2/3 ( 18+25/30)

->  -1/15 + (-5/6) = -2/3 (43/30)

->  -5+(-10)/30 = - 86/90

->  -15/30 = -43/45

->  -15*45 = -43*30

-> -135 = -1290

-> 135 = 1290

Hence proven, they are not equal.
