Answer 1

Calculation of Fractions

Let's calculate the given fractions step by step:

1) 1/5 - 1/6: To subtract fractions, we need to find a common denominator. In this case, the common denominator is 30. So, we have: - 1/5 = 6/30 - 1/6 = 5/30

Now, we can subtract the fractions: - 6/30 - 5/30 = 1/30

Therefore, 1/5 - 1/6 = 1/30.

2) 3/4 - 1/3: Again, we need to find a common denominator, which is 12 in this case. So, we have: - 3/4 = 9/12 - 1/3 = 4/12

Now, we can subtract the fractions: - 9/12 - 4/12 = 5/12

Therefore, 3/4 - 1/3 = 5/12.

3) 7/9 - 2/11: Finding a common denominator, which is 99: - 7/9 = 77/99 - 2/11 = 18/99

Now, we can subtract the fractions: - 77/99 - 18/99 = 59/99

Therefore, 7/9 - 2/11 = 59/99.

4) 3/4 - 4/9: Finding a common denominator, which is 36: - 3/4 = 27/36 - 4/9 = 16/36

Now, we can subtract the fractions: - 27/36 - 16/36 = 11/36

Therefore, 3/4 - 4/9 = 11/36.

5) 7/8 - 5/12: Finding a common denominator, which is 24: - 7/8 = 21/24 - 5/12 = 10/24

Now, we can subtract the fractions: - 21/24 - 10/24 = 11/24

Therefore, 7/8 - 5/12 = 11/24.

6) 11/12 - 11/18: Finding a common denominator, which is 36: - 11/12 = 33/36 - 11/18 = 22/36

Now, we can subtract the fractions: - 33/36 - 22/36 = 11/36

Therefore, 11/12 - 11/18 = 11/36.

I hope this helps! Let me know if you have any further questions.
