15. (2/3)-( 7/4)

Answer 1

1. 9/18+(-4/18) = 5/18

2. 7/4-(-11/4) = 7/4 + 11/4  = 18/4 = 9/2

3. 3/4) -(5/4)  = -2/4= -1/2

4. (-19/101) +(-8/101) = -19/101 -8/101 = -27/101

5. (-17/8) -5/8 = -22/8 = -11/4

6. (- 19/2) +13/2  = -6/2 = -3

7. 6/9 -(-3/4) = 24/36 +27/36 = 51/36 = 17/12

8. (-3/4) +(-1/5) = -15/20 -4/20 = -19/20

9.(-1/5)-(-3/7)=  -7/35 + 15/35 = 8/35

10. (-12/9)+(-1/6) = -4/3 - 1/6 = -24/18 -3/18 = -27/18 = -3/2

11. 13/5- 19/2 = 26/10 - 95/10 = -69/10

12. (-8/5)+ 1/7 = -56/35 + 5/35 = -51/35

13. (- 1/4)- 12/20 = -5/20 - 12/20 = -17/20

14. ( -3 2/5) +(- 5/3) = -17/5 -5/3 = -51/15 - 25/15  = 76/15

15. (2/3)-( 7/4) = 8/12 - 21/12 = -13/12
