Question

1/2x(-2/5+-3/7)=(1/3x-2/5)+(1/3x-3/7)
pls answer quick it's urgent

Answer 1

(1/3×-2/5)+(1/3×-3/7)
taking out 1/3 as common.
=1/3 (-2/5+-3/7 ) [also known as distributive law]
=1/3 [{(-2)7+(-3)5}/35]
=1/3 {-14-15/35}
=1/3 × -27/35
=-27/105
=-9/35

Answer 2

1/3× [-14/35+(-15)/35]=[-2/15]+[-3/21]

1/3×[-29/35]=-2/15+(-3)/21

-29/105=-14/105-15/105

-29/105= -29/105

Hence, L.H.S=R.H.S
