3. Which is bigger, 20 / 7, 25 / 8, 19 / 6, or 1 / 35

3. Which is bigger, 20 / 7, 25 / 8, 19 / 6, or 1 / 35

Nineteen out of six, for the following reasons:
One in 35 is less than one, obviously the smallest;
Twenty out of seven are less than three, and the second is the smallest,
Twenty five eighths and nineteen sixths are bigger than three, one eighth and one sixth. Because one sixth is bigger than one eighth, nineteen sixths is the biggest

The simple calculation method is as follows: 1. 14 / 15 × 7 2. 19 / 20 times 6 × 6 3. 127 × 4 / 25 4. 98 × 9 / 9 5

19 / 20 times 6 × 63 = (1-1 / 20) * 63 = 63-63 / 20 = 59 and 17 / 203.127 × 4 / 25 (125 + 2) * 4 / 25 = 20 + 8 / 25 = 20 and 8 / 254.98 × 5 / 99 = (99-1) * 5 / 99 = 5-5 / 99 = 4 and 94 / 99

2U / 3 + 3U / 4 = 4U / 2 + 5 ∪ = 7 / 15

Questions: 2U / 3 + 3U / 4 =. 5; 4U / 5 + 5u / 6 = 7 / 15
The result is: 17u / 12 = 1 / 2, that is, u = 6 / 17
The second formula is 49U / 30 = 7 / 15, that is, u = 2 / 7
What do you want to ask,

(1) 6 and 10 of 1 = 5 and 10 of () = 4 and 10 of () = 3 and 10 of () = 2 and 10 of ()
(2) . 5 and 8 of 7 = 4 and 8 of () = 3 and 8 of () = 2 and 8 of () = 1 and 8 of () PS: the fraction with fraction must be true fraction!
