Question

2/5x(-3/5)-1/6x3/2+1/14x2/5​

Answer 1

Answer:

2/3 x 3/5 + 5/2 - 3/5 x 1/6 = -2/3 x 3/5 - 3/5 x 1/6 + 5/2 [by commutativity] = (-2/3 x 3/5) - (3/5 x 1/6) + 5/2 = 3/5 [-2/3 - 1/6] + 5/2 [by distributivity] = -3/5 [2/3 + 1/6] + 5/2 = -3/5 [(4 + 1)/6] + 5/2 = -3/5 x 5/6 + 5/2 = -3/6 + 5/2 = -1/2 + 5/2 = (-1 + 5)/2 = 4/2 = 2
