Answer 1

Respuestas:

a. 3/5 + 7/5 = 10/5 = 2

b. 1/2 + 1/4= 2/4 + 1/4= 3/4

c. 2/3 + 1/6 = 4/6 + 1/6 = 5/6

d. 6/5 + 7/4 = 24/20 + 35/20 = 59/20 = 2 19/20

e. 10/6 + 1/2 = 10/6 + 3/6 = 13/6 = 2 1/6

f. 12/5 + 19/3 = 36/15 + 95/15 = 131/15 = 8 11/15

a. 2/6 + 1/6 + 3/6 = 6/6 = 1

b. 2/5 + 3/4 + 5/2 = 8/20 + 15/20 + 50/20 = 73/20 = 3 13/20

c. 2/9 + 1/3 + 5/6 + 3/4 =

2×4/9×4= 8/36

1×12/3×12= 12/36

5×6/6×6= 30/36

3×9/4×9= 27/36

8/36 + 12/36 + 30/36 + 27/36 = 77/36 = 2 5/36

d. 15/6 + 2/3 + 1/2+ 5/12 =

15×2/6×2= 30/12

2×4/3×4= 8/12

1×6/2×6= 6/12

5/12

30/12 + 8/12 + 6/12 + 5/12 = 49/12 = 4 1/12

a. 9/8 - 3/8 = 6/8 = 3/4

b. 5/10 - 1/4=

5×4/10×4= 20/40

1×10/4×10= 10/40

b. 20/40 - 10/40 = 10/40 = 1/4
