For 7/60 and 9/20:

To compare fractions, we need to find a common denominator. In this case, the least common denominator is 60.

7/60 = 7 1 / 60 = 7/60
9/20 = 9 3 / 20 * 3 = 27/60

Now we have:

7/60 = 7/60
9/20 = 27/60

Since 27/60 is greater than 7/60, 9/20 is greater than 7/60.

For 52/105 and 61/630:

Again, we need to find a common denominator. In this case, the least common denominator is 630.

52/105 = 52 6 / 105 6 = 312/630
61/630 = 61/630

Now we have:

52/105 = 312/630
61/630 = 61/630

Since 312/630 is greater than 61/630, 52/105 is greater than 61/630.
