Answer 3

To solve this equation, we need to find a common denominator for all fractions involved. The common denominator for 3, 5, and 12 is 60.

Now, let's convert the fractions to have a denominator of 60:

1/3 * 20/20 = 20/60 4/5 * 12/12 = 48/60 1/12 * 5/5 = 5/60

Now the equation becomes:

20/60 + 48/60 - 5/60

To combine the fractions, we simply add or subtract the numerators while keeping the denominator the same:

(20 + 48 - 5)/60 = 63/60

However, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

63/3 = 21 60/3 = 20

So the simplified fraction is:

21/20

Therefore, 1/3 + 4/5 - 1/12 equals 21/20.
