To find fractions smaller than each given fraction, we can reduce the numerator while keeping the denominator constant. Here are five fractions smaller than each given fraction:

1/2:
- 1/3
- 1/4
- 1/5
- 1/6
- 1/7

1/4:
- 1/5
- 1/6
- 1/7
- 1/8
- 1/9

2/5:
- 2/6
- 2/7
- 2/8
- 2/9
- 2/10

3/8:
- 3/9
- 3/10
- 3/11
- 3/12
- 3/13

3/10:
- 3/11
- 3/12
- 3/13
- 3/14
- 3/15

To find fractions that are smaller than the given fractions, you need to consider fractions with a smaller numerator and a larger denominator.

For 1/2:
- 1/3: The numerator is smaller (1 < 2) and the denominator is larger (3 > 2).
- 1/4: The numerator is smaller (1 < 2) and the denominator is larger (4 > 2).
- 1/5: The numerator is smaller (1 < 2) and the denominator is larger (5 > 2).

For 1/4:
- 1/5: The numerator is smaller (1 < 4) and the denominator is larger (5 > 4).
- 1/6: The numerator is smaller (1 < 4) and the denominator is larger (6 > 4).
- 1/7: The numerator is smaller (1 < 4) and the denominator is larger (7 > 4).

For 2/5:
- 1/3: The numerator is smaller (1 < 2) and the denominator is larger (3 > 5).
- 1/4: The numerator is smaller (1 < 2) and the denominator is larger (4 > 5).
- 1/6: The numerator is smaller (1 < 2) and the denominator is larger (6 > 5).

For 3/8:
- 1/4: The numerator is smaller (1 < 3) and the denominator is larger (4 > 8).
- 1/5: The numerator is smaller (1 < 3) and the denominator is larger (5 > 8).
- 1/6: The numerator is smaller (1 < 3) and the denominator is larger (6 > 8).

For 3/10:
- 1/4: The numerator is smaller (1 < 3) and the denominator is larger (4 > 10).
- 1/5: The numerator is smaller (1 < 3) and the denominator is larger (5 > 10).
- 1/6: The numerator is smaller (1 < 3) and the denominator is larger (6 > 10).

So, the fractions that are smaller than the given fractions are:
1/3, 1/4, 1/5 for 1/2;
1/5, 1/6, 1/7 for 1/4;
1/3, 1/4, 1/6 for 2/5;
1/4, 1/5, 1/6 for 3/8; and
1/4, 1/5, 1/6 for 3/10.

for a smaller fraction, keep the numerator the same, but make the denominator bigger
