Hi ,
**************"*****************
If a , b , c are Rational numbers ,
a × b + a × c = a ( b + c )
Distributive property
**************************************
Here
a = 7/5 ,
b = ( -3/12 ) ,
c = 5/12 ,
[ 7/5 × ( -3/12 ) ] + [ 7/5 × 5/12 ]
= 7/5 × [ -3/12 + 5/12 ]
= 7/5 × ( 2/12 )
= ( 7 × 2 )/ ( 5 × 12 )
after cancellation
= 7/30
I hope this helps you.
