Fraction subtraction with simple fractions

Teaching Transcript

🎙️

Let's subtract one third from one half

First find a common denominator. The lowest common multiple of 3 and 2 is 6

Converting both fractions, we have 3 over 6, minus 2 over 6

Now that the denominators are the same we can subtract the numerators. 3 minus 2 is 1, so our answer is one sixth

This math skill involves subtracting simple fractions by finding a common denominator, converting the fractions, and then subtracting the numerators to find the result.
