Answer 1

1. (-3×2 + 5 - 7)/4 = (-6+5-7)/4 = -8/4 = -2

2. {5×3 - 7×2 -(-2×4)}/12 =

{ 15 - 14 + 8 }/12 = 9/12 = 3/4

3. {(-2×14) - (-3×7) - (-4×10)}/70

= { -28 + 21 + 40 }/70 = 43/70

Answer 2

Hey mate let me tell you all are verified answer so the answer given before was wrong.....

Answer:

1.-3/8+5/4-7/4

-3/8+5/4-7/4=(-3+10-14)/8

-3/8+5/4-7/4=(-3+10-14)/8=-17+10

-3/8+5/4-7/4=(-3+10-14)/8=-17+10=-7/8
