Vì +7=1 nên suy ra tử+7 = mẫu. Mà khi tử chưa bằng mẫu thì =25 mà khi tử =mẫu là 25+7=32. Mẫu số là:32÷2=16
Tử số là:16-7=9
Do là 2 số lẻ liên tiếp nên hiệu của chúng sẽ bằng 2
Phân số < 1 nên suy ra tử số < mẫu số
Tử số là: (104 - 2) : 2 = 51
Mẫu số là: 51 + 2 = 53
⇒ Phân số đó là: \(\dfrac{51}{53}\)
Tử số và mẫu số của một phân số nhỏ hơn 1 là hai số lẻ liên tiếp thì tử số nhỏ hơn mẫu số 2 đơn vị.
tử số là:
(104-2):2=51
mẫu sớ là:
104-51=53
vậy phần số đó là:51/53
Zero ; One ; Two ; Three ; Four ; Six ; Seven ; Eight ; Nine ; Ten
Ko viết đc 5 dòng
mình cần gấp
a: 6/7=1-1/7
5/6=1-1/6
mà -1/7>-1/6
nên 6/7>5/6
b: 11/10>1>10/11
c: 18/36=3/6<7/6
