Answer 2

To solve these expressions, we need to find a common denominator and then add or subtract the fractions. Here are the solutions to the given expressions:

1. 5/9 + 1/6 + 3/4:

   To find the common denominator, we need to find the least common multiple of 9, 6, and 4, which is 36.

   Then, we can rewrite each fraction with a denominator of 36:

   5/9 = 20/36 1/6 = 6/36 3/4 = 27/36

   Now, we can add the fractions:

   20/36 + 6/36 + 27/36 = 53/36

   Therefore, 5/9 + 1/6 + 3/4 = 53/36.

2. 1/3 + 4/9 + 5/6:

   To find the common denominator, we need to find the least common multiple of 3, 9, and 6, which is 18.

   Then, we can rewrite each fraction with a denominator of 18:

   1/3 = 6/18 4/9 = 8/18 5/6 = 15/18

   Now, we can add the fractions:

   6/18 + 8/18 + 15/18 = 29/18

   Therefore, 1/3 + 4/9 + 5/6 = 29/18.

3. 1/4 + 1/5 - 3/10:

   To find the common denominator, we need to find the least common multiple of 4, 5, and 10, which is 20.

   Then, we can rewrite each fraction with a denominator of 20:

   1/4 = 5/20 1/5 = 4/20 3/10 = 6/20

   Now, we can subtract the fractions:

   5/20 + 4/20 - 6/20 = 3/20

   Therefore, 1/4 + 1/5 - 3/10 = 3/20.
