Question

Using appropriate properties find
2/5*(-3/7)-1/6*3/2+1/14*7/5​

Answer 1

Answer:

(i) -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
