Answer 2

1. 9 1/26 - 7: To subtract mixed numbers, we need to convert them to improper fractions first.

9 1/26 = (9 * 26 + 1) / 26 = 235 / 26 7 = 7/1

Now, we can subtract the fractions:

235/26 - 7/1

To subtract fractions, we need a common denominator. The common denominator here is 26:

(235 - (7 * 26)) / 26 = (235 - 182) / 26 = 53 / 26

So, 9 1/26 - 7 = 53/26.

2. 9 23/33 - 23/33: Here, we have the same denominator, so we can directly subtract the fractions:

9 23/33 - 23/33 = (9 * 33 + 23) / 33 - 23/33 = (297 + 23) / 33 - 23/33 = 320 / 33 - 23/33 = (320 - 23) / 33 = 297/33 = 9

So, 9 23/33 - 23/33 = 9.

3. 10 1/16 - 1/5: To subtract mixed numbers, we need to convert them to improper fractions:

10 1/16 = (10 * 16 + 1) / 16 = 161 / 16 1/5 = 1/5

Now, we can subtract the fractions:

161/16 - 1/5

To subtract fractions, we need a common denominator. The least common multiple of 16 and 5 is 80:

(161 * 5 - 1 * 16) / 80 = (805 - 16) / 80 = 789/80

So, 10 1/16 - 1/5 = 789/80.

4. 58/77 - 16/77: The fractions have the same denominator, so we can directly subtract them:

58/77 - 16/77 = (58 - 16) / 77 = 42/77 = 6/11

So, 58/77 - 16/77 = 6/11.

5. 4 - 2 29/30: To subtract mixed numbers, we need to convert them to improper fractions:

4 = 4/1 2 29/30 = (2 * 30 + 29) / 30 = 89/30

Now, we can subtract the fractions:

4/1 - 89/30

To subtract fractions, we need a common denominator. The common denominator here is 30:

(4 * 30 - 89 * 1) / 30 = (120 - 89) / 30 = 31/30

So, 4 - 2 29/30 = 31/30.
