Answer:
3/4×(-6/7+2/5)=3/4×-6/7+3/4×2/5
3/4×(-30+14/35)=-18/28+6/20
3/4×-16/35=-9/14+3/10
-48/140=-90+42/140
-48/140=-48/140

Solution.)
Substitute the values =
A=3/4 * (b-6/7 + c-2/5)
BODMAS rule =
-6/7 + -2/5 = lcm = 35
-6*5/7*5 + -2*7/5*7
= -30/35 + -14/35
= -44/35
= 3/4*-44/35
= Answer= -132/140
Substitute the values =
A=3/4 * (b-6/7 + c-2/5)
BODMAS rule =
-6/7 + -2/5 = lcm = 35
-6*5/7*5 + -2*7/5*7
= -30/35 + -14/35
= -44/35
= 3/4*-44/35
= Answer= -132/140
