a) (2 – 1/5)²/(3 – 2/9)⁻¹ ÷ [(6/7 x 5/4) – (2/7 : 1/2)]³/[(1/2 – 1/3 ) x (1/4 : 1/5)] – 5 1/7 =
Resolviendo.
(9/5)²/(25/9)⁻¹ ÷ [(30/28) – (2/7 - 4/7)]³/[(1/6) x (5/4)] – 36/7
81/25 x 25/9 ÷ [(30/28) – (8/49)]/(52/4) – 36/7
(81/9 ÷ 89/98) ÷ 55/7
81 x 98/9 x 89 ÷ 55/7
7938/801 ÷ 55/7
7938 x 7/801 x 55
55.566/44.055 =
6.174/4.895 = 1,26
b) [(2/3 – 1/9) + 13(2/3 – 1)²] : [(1/2 – 1) : 2 ½] =
[(5/3) + 13(–1/3)²] : [(– 1/2) : 5/2] =
[(5/3) + 13(1/9)] : [(– 1/2) : 5/2] =
[5/3 + 13/9] : [– 2/10] =
[28/3] : [– 2/10] =
280/- 6
- 140/3 = 46,6…
c) 2/3 : [5 : (2/4 + 1) – 3(1/2 – 1/4)] =
2/3 : [5 : (3/2) – 3(1/4)]
2/3 : [5 : (3/2) – (3/4)]
2/3 : [5 : (3/4)]
2/3 : [20/3]
6/60
1/10 = 0,1
d) (3/2 + 1/4)/(5/6 – 1/3) =
7/6 ÷ 3/2 = 14/18
7/9= 0,7…
e) (– 1 + 3/4 – 1/3)/(2 – 1/4)
– 7/12 ÷ 7/4
– 28/84
– 1/3 = 0,3….
f) [1 – (1/(1 – 1/(1 – 1/2))]
[1 – (1/(1 – 1/(1/2)))]
[1 – (1/(1 – 2))]
[1 – (1/(– 1))]
[1 – (– 1)]
[1 + 1] = 2
