Answer 1

To subtract fractions, find a common denominator, subtract the numerators, and simplify the result.

Step-by-step explanation:

To subtract fractions, you need to have a common denominator. If the two fractions don't already have a common denominator, you need to find the least common multiple (LCM) of the denominators and then convert both fractions to have that LCM as the denominator. Once you have a common denominator, you can subtract the fractions by subtracting the numerators and keeping the denominator the same. Simplify the resulting fraction, if necessary, by reducing it to its lowest terms.

Example:

A. 4/5 - 1/2:

The least common multiple of 5 and 2 is 10. Convert 4/5 to 8/10 and 1/2 to 5/10. Now you can subtract the fractions: 8/10 - 5/10 = (8 - 5)/10 = 3/10. The answer is 3/10.
