Answer 1

Answer:

Hii buddy there is your answer

Step-by-step explanation:

Using appropriate properties, find:

(i) -2/3 * 3/5 + 5/2 – 3/5 * 1/6                  (ii) 2/5 * (3/-7) – 1/6 * 3/2 + 1/14 * 2/5

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
