estimate 5/8 - 1/10 as a fraction

Answer 1

To subtract fractions, we first need to find a common denominator. In this case, the common denominator is 40, which is the product of 8 and 10.

Now, let's convert both fractions to have a denominator of 40:

5/8 * 5/5 = 25/40
1/10 * 4/4 = 4/40

Now, we can subtract the fractions:

25/40 - 4/40 = (25 - 4) / 40 = 21/40

Therefore, 5/8 - 1/10 is equal to 21/40.
