what is 11/15 - 7/20

The common denominator is 60

44/60 - 21/60 = 23/60

Math

To subtract fractions, you need a common denominator. Let's find the common denominator for 15 and 20.

The least common multiple (LCM) of 15 and 20 is 60. Therefore, we can rewrite the fractions with a common denominator of 60:

11/15 = (11/15) * (4/4) = 44/60
7/20 = (7/20) * (3/3) = 21/60

Now, we can subtract these fractions:

44/60 - 21/60 = (44 - 21)/60 = 23/60

So, 11/15 - 7/20 = 23/60.

To find the difference between 11/15 and 7/20, you need to have a common denominator for both fractions. The least common multiple (LCM) of 15 and 20 is 60, so we can rewrite the fractions with the common denominator of 60.

11/15 becomes (11/15) * (4/4) = 44/60
7/20 becomes (7/20) * (3/3) = 21/60

Now we can subtract the fractions:
44/60 - 21/60 = (44 - 21)/60 = 23/60

Therefore, the difference between 11/15 and 7/20 is 23/60.
