Răspuns:

Explicație pas cu pas:

b) = 7/2 : 1/10 + 9/10 = 7/2 × 10 + 9/10 = 7×5 +9/10 =

= 35 +9/10 = (350+9)/10 = 359/10

c) = 27/5 - 4 : 5/3 = 27/5 - 4 × 3/5 = 27/5 - 12/5 = 15/5 = 3

g) = (22/3 + 9/4):1/4 - 185/6 = (88+27/12)×4-185/6 =

= 115/12 × 4 - 185/6 = 115/3 - 185/6 = (230-185)/6 =

= 45/6 = 15/2.
