What is 1/12 - 3/4 show me how to do it

Answer 1

To subtract fractions, you need to have a common denominator. In this case, the common denominator for 1/12 and 3/4 is 12.

First, convert 3/4 into twelfths by multiplying the numerator and denominator by 3:
3/4 = (3 * 3)/(4 * 3) = 9/12

Now that both fractions have the same denominator, you can subtract the numerators:
1/12 - 9/12 = (1 - 9)/12 = -8/12

However, the resulting fraction can be simplified. Both the numerator and denominator are divisible by 4:
-8/12 = (-8/4) / (12/4) = -2/3

So, 1/12 - 3/4 = -2/3.
