Question

I need 5,6,7,9,10,12​

Answer 1

4 : 2/11 × 14/-5 = 28/-55

5: 2/5×35/6 + 1/3×12/11

70/30 + 12/33

7×11/3×11 + 12×1/33×1 = 77+12/33 = 89/33

6: 5+(-2)/4 + -3/2 = 5/4 + -4/2

3+(-6)/4 = 5+(-8)/4

-3/4 = -3/4

7 : 3/5 + -2/5 + 7/3 + -2/3

3+ (-2)/5 + 7+(-2)/3

1/5 + 5/3 = 3/15 + 25/15= 28/15

8:.1 1/3 - 3/4

1×4/3×4 - 3×3/4×3 = 4-9/12 = -3/12

2: 2/1 - 32/13

2×13/1×13 - (-32)×1/13×1

26-(-32)/13 = 58/13

3: -4/7 - (-7)/1

-4×1/7×1 - (-7)×1/1×7

-4-(-7)/7 = -3/7

9 : -5/8 - (-3)/2 = -5×1/8×1 - (-3×4)/2×4

-5-(-12)/8 = -7/8

10: -5/6- 8/1 = -5×1/6×1 - 8×6/1×6

-5-48/6 = 53/6
