Answer 1

Respuesta:

a)

9/5 + 7/8 + 1/10

72/40 + 35/40 + 4/40 = 111/40 o 2.775

b)

-6 + 7.87 - 4.23

-10.23 + 7.87 = -2.36

c)

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

2/7 - 7/2 - 3/2

4/14 - 49/14 - 21/14

4/14 - 70/40 = -66/40 o -1.65

d)

7.2 + (-6.81) - 10.3

7.2 - 6.81 - 10.3

7.2 -17.11 = -9.91

e)

17/8 + (-5/8) - 7/8

17/8 - 5/8 - 7/8

17/8 - 12/8 = 5/8 o 0.625

f)

1/7 + 3/5 + 5/7

5/35 + 21/35 + 25/35 = 51/35 o 1.45

g)

3.9 + 5.23 + 6.03 = 15.16
