Answer 2

To add and subtract these fractions, you'll need to find a common denominator. The common denominator for 2/3, 3/5, and 1/2 is 30. Here's how you can do the calculations step by step:

1. Convert 1/2 to an equivalent fraction with a denominator of 30: (1/2) * (15/15) = 15/30

2. Convert 3/5 to an equivalent fraction with a denominator of 30: (3/5) * (6/6) = 18/30

Now that all the fractions have the same denominator, you can add and subtract them:

(15/30) + (18/30) - (2/3)

Now, add and subtract the fractions:

(15/30) + (18/30) - (2/3) = (15 + 18)/30 - (2/3) = 33/30 - (2/3)

To subtract the fractions, make sure they have the same denominator:

(33/30) - (2/3)

To subtract these fractions, you'll want to find a common denominator for 30 and 3, which is 30. Then, perform the subtraction:

(33/30) - (2/3) = (33/30) - (20/30)

Now that the fractions have the same denominator, subtract the numerators:

(33/30) - (20/30) = (33 - 20)/30 = 13/30

So, the result of the expression 1/2 + 3/5 - 2/3 is 13/30.
