Question

Using appropriate properties find 2/3x3/5+5/2-3/5x1/6

Please answer quickly.​

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

( Using commutativity of rational number)

= (-3/5) x (2/3 + 1/6) + 5/2  (Distributivity)

= (-3/5) x (2x2 + 1/6) + 5/2 = 0-3/5) x (5/6) + 5/2

= (-3/6) + 5/2 = (-3+5 x 3/6) = (-3 + 15/6)

= 12/6 = 2
