Answer 1

Calculation of Fractions

Let's calculate the following expressions step by step:

1. 3/8 + 1/4: To add fractions, we need to have a common denominator. In this case, the common denominator is 8. So, we rewrite the fractions as follows: 3/8 + 1/4 = (3/8) + (2/8) = 5/8.

2. 2/3 - 1/6: To subtract fractions, we also need a common denominator. In this case, the common denominator is 6. So, we rewrite the fractions as follows: 2/3 - 1/6 = (4/6) - (1/6) = 3/6 = 1/2.

3. 7/12 - 1/2: Again, we need a common denominator to subtract fractions. The common denominator here is 12. So, we rewrite the fractions as follows: 7/12 - 1/2 = (7/12) - (6/12) = 1/12.

4. 2/9 + 2/3: To add fractions, we need a common denominator. In this case, the common denominator is 9. So, we rewrite the fractions as follows: 2/9 + 2/3 = (2/9) + (6/9) = 8/9.

Therefore, the results of the given expressions are: - 3/8 + 1/4 = 5/8 - 2/3 - 1/6 = 1/2 - 7/12 - 1/2 = 1/12 - 2/9 + 2/3 = 8/9.

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