0,(571428) = 571428/999999 = 4/7
2,01(6) = 2,01 + 6/900 = 121/60
0,1(63) = 0,1 + 63/990 = 9/55
2,41(3) = 2,41 + 3/900 = 181/75
0,88(63) = 0,88 + 63/9900 = 39/44

A= \(\frac{3}{2.2}\) = 0.75
A = \(\frac{3}{2.3}\) = 0.5
A= \(\frac{3}{2.5}\) = 0.3
Chúc bạn học tốt

Ukm
It's very hard
l can't do it
Sorry!
Ta có: 0,(63) = \(\frac{7}{11}\)
0,6(36) = \(\frac{636-6}{990}\) = \(\frac{630}{990}\) = \(\frac{7}{11}\)
có: \(\frac{7}{11}\) = \(\frac{7}{11}\) => 0,(63) = 0,6(36)
sao lại từ 0, 6(36) lạ ra cái: \(\frac{636-6}{990}\) ?
