Here's how to subtract 3/8 from 5/8:


Step 1Since our denominators match, we can subtract the numerators. 5 − 3 = 2 So the answer is:


Step 2Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? To find out, we try dividing it by 2... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by 2 again... No good. 2 is larger than 1. So we're done reducing. There you have it! The final answer is:
