"Come first" is a subjective description.
The order largest to smallest is 13/5, 52/25, 7/8 & 13/20 but they could just as well be listed smallest to largest.
If your working with fractions then you can't simplify it so it is 13/20 . And if it isn't fractions then it is 6.5/10
11/13, 22/26
There are an infinite number of such fractions. 14/26, 21/39 are two examples.
18/35 + 13/42 = 1211/1470 or 173/210
130/240, 26/48 are two.
To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified: 7/13 - 1/18 = 126/234 - 13/234 = 113/234
26 over 48

13/159 is already at its lowest terms
13/100 is equivalent to 26/200 as a fraction
11/13 = 22/26 = 33/39
11/13, 22/26
7/13 + 2/7 = 75/91
There are an infinite number of such fractions. 14/26, 21/39 are two examples.
18/35 + 13/42 = 1211/1470 or 173/210
They are: 7/13 and 14/26
