Câu 2:
1)Chứng minh các phân số bằng nhau:
41/88, 4141/8888, 414141/888888
2)Chứng minh:12n+1/30n+2(n thuộc Z) tối giản.
1) 4141 / 8888 = 4141 : 101 / 8888 : 101 = 41 / 8
414141 / 888888 = 414141 : 10101 / 888888 : 10101 = 41/ 8
=> 41 / 88 = 4141/8888 = 414141/888888
2) Gọi a là ƯCLN của tử số và mẫu số
Vì: 12n + 1 chia hết cho a
30n + 2 chia hết cho a
=> 60n + 5 chia hết cho a
60n + 4 chia hết cho a
Nên: (60n + 5) - (60n + 4) chia hết cho a
=> 1 chia hết cho a
=> a = 1
=> Ư CLN (12n+1, 30n+2) = 1
Vậy 12n+1 /30n+2 là phân số tối giản
