Question

class 8th chapter 1 rational number​

Answer 1

Answer:

Step-by-step explanation:

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

    2/3 +(24+(-29))/30  = (10+12)/15 -5/6

    2/3 -1/30 =22/15 -5/6

    20-1/30 = 132-75/ 90

    19/30 = 19/30

    2/3*(4/5*5/6) = (2/3*4/5)*5/6

    2/3*2/3 = 8/15*5/6

    4/9 = 4/9
