Answer 1

Respuesta:

5/12, 99/28, 179/20, 23/4 y 19/9

Explicación paso a paso:

a) 3/4 - 0.2... x 3/2 = 3/4 - 2/9 x 3/2 = 3/4 - 1/3 = 9-4/12 = 5/12

b) 0.25 / (-7/8) - 13/4 = (1/4) /(-7/8) - 13/4 = -8/28 - 13/4 = -8 - 91/28 = 99/28

c) 21/3 - 3/10 x 2.2... = 21/3 - 3/10 x 13/2 = 21/3 - 39/20 = -420 - 117/60 = 537/60 = 179/20

d) 1.2... x 3/2 - 5/2 = 11/2 x 3/2 - 5/2 = 33/4 - 5/2 = 33 - 10/4 = 23/4

e) -0.02... - 4/3 / (-8/5) = -1/45 - (4/3)/(-8/5) = -1/45 + 32/15 = -1 + 96/45 = 95/45

19/9
