if you divide the numerator by the denominator using a calculator, you will be able to see the values in a more numerical fashion and organize them from there.
for example, for part a,
3 divided by 5 = 0.6
1 divided by 6 = 1.666
2 divided by 3 = 0.666
meaning your answer would be 3/5, 2/3, and 1/6 if arranged in increasing order.
b) 1/3, 1/2, 5/7
c) 1/5, 3/4, 7/8
d) 1/2, 2/3, 7/10, 4/5
e) 1/2, 2/3, 5/6, 8/9
f) 2/5, 1/2, 7/10, 3/4
