To subtract these mixed numbers, we first need to convert them to improper fractions.
15 3/8 can be converted to an improper fraction:
15 3/8 = (15 * 8 + 3)/8 = 123/8
11 1/5 can be converted to an improper fraction:
11 1/5 = (11 * 5 + 1)/5 = 56/5
Now we can subtract the fractions:
(123/8) - (56/5)
To subtract fractions, we need to find a common denominator. In this case, the common denominator is 40 because both 8 and 5 can be divided evenly into it.
(123/8) = (123/8) * (5/5) = (615/40)
(56/5) = (56/5) * (8/8) = (448/40)
Now we can subtract:
(615/40) - (448/40) = (615 - 448)/40 = 167/40
Therefore, 15 3/8 - 11 1/5 = 167/40 as an improper fraction.
