Question

CALCULE E SIMPLIFIQUE OS RESULTADOS QUANDO FOR POSSÍVEL​

Answer 1

Resposta:

a)1/2-1/3 = (6÷2×1)-(6÷3×1)/6 = (3×1)-(2×1)/6 = 3-2/6 = 1/6

b)5/6-1/3 = (6÷6×5)-(6÷3×1)/6 = (1×5)-(2×1)/6 = 5-2/6 = 3/6 = 3÷3/6÷3 = 1/2

c)4/5-2/7 = (35÷5×4)-(35÷7×2)/35 = (7×4)-(5×2)/35 = 28-10/35 = 18/35

d)7/8-1/6 = (24÷8×7)-(24÷6×1)/24 = (3×7)-(4×1) 21-4/24 = 17/24

e)5/4-1/2 = (4÷4×5)-(4÷2×1)/4 = (1×5)-(2×1)/4 = 5-2/4 = 3/4

f)8/10-1/5 = (10÷10×8)-(10÷5×2)/10 = (1×8)-(2×2)/10 = 8-4/10 = 4/10 = 4÷2/10÷2 = 2/5
