Question

(1/3+4/5)+(-1/6)=1/3+(4/5+(-1/6))​

Answer 1

Answer:

i) -2/3 * 3/5 + 5/2 – 3/5 * 1/6

  = -2/3 * 3/5 – 3/5 * 1/6 + 5/2             [Using associative property]

  = 3/5 * (-2/3 – 1/6) + 5/2                    [Using distributive property]

  = 3/5 * {(-4 - 1)/6} + 5/2                      [LCM (3, 2) = 6]  

  = 3/5 * (-5/6) + 5/2

  = -3/6 + 5/2

  = -1/2 + 5/2

  = (-1 + 5)/2

  = 4/2

  = 2
