2) 1 17/28

3) 7 1/2

4) 2 2/21

5) 2/9

6) 2 1/4

7) 2 6/25

Explicación paso a paso:

1) 8/12+2/5-1/2-1/10

2/3+2/5-1/2-1/10

20+12-15-3/30=14/30= 7/15

2) 3/2x15/14= 3×15/2×14=45/28 = 1 17/28

3) 6x5/4= 6×5/1×4= 30/4 = 7 1/2

4) 4/3:7/11= 4×11/3×7= 44/21= 2 2/21

5) 4/3:6= 4×1/3×6= 4/18 = 2/9

6) 6/7x(9/4+3/8)

6/7(18+3/8)

6/7× 21/8= 126/56= 9/4 = 2 1/4

7) (8+2/5):(6-9/4)

(40+2/5)÷(24-9/4)

42/5÷15/4

42×4/5×15 =168/75 = 56/25= 2 6/25
