Question

2 by 5 into (minus 3 by 7) minus 1 by 6 into 3 by 2 + 1 by 14 into 2 by 5 (With explanation)

Answer 1

Answer:

2/5 × -3/7 = -6/35

1/6×3/2=1/4

1/14×2/5=1/35

-6/35×1/4=-3/70

=-1/70

Answer 2

Answer: simplify 2/5×-(3/7)-1/6×3/2+1/14×2/5

Rearranging the terms , we get

= [2/5 ×(-3/7)+(1/14)(2/5)]-1/6×3/2

= (2/5)[ -3/7 +1/14] - 1/4

By Distributive property:

A×B + A×C = A(B+C)

=(2/5) [ (-6+1)/14] - 1/4

= (2/5)×(-5/14) - 1/4

= -1/7 - 1/4 /* After cancellation */

=( -4 - 7)/28

= -11/28

Therefore,

2/5×-(3/7)-1/6×3/2+1/14×2/5

= -11/28
