Question

find using appropriate properties


2/5 × -3/7 - 1/6 × 3/2 +1/14 ×2/5​

Answer 1

Step-by-step explanation:

=2/5 ×(3/7 - 1/6 + 1/14)

=2/5 × (11/42 +1/14)

=2/5 × 1/14

=2/70

Answer 2

Answer:

= – 11/28

Step-by-step explanation:

Solution:

2/5 × (- 3/7) – 1/6 × 3/2 + 1/14 × 2/5

= 2/5 × (- 3/7) + 1/14 × 2/5 – (1/6 × 3/2) (by commutativity)

= 2/5 × (- 3/7 + 1/14) – 3/12

= 2/5 × ((- 6 + 1)/14) – 3/12

= 2/5 × ((- 5)/14)) – 1/4

= (-10/70) – 1/4

= – 1/7 – 1/4

= (– 4– 7)/28
