The easiest way to work out 22 x 1 3/8 is to convert the mixed number to an improper fraction, do the multiplication and convert the resulting improper fraction back to a mixed number:

1 3/8 = 11/8

22 x 1 3/8 = 22 x 11/8

= 242/8

= 121/4 (divide top and bottom by 2)

= 30 1/4

To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator to give the new numerator; the denominator stays the same.

Example: 1 3/8 => (1 x 8 + 3)/8 = 11/8

To convert an improper fraction to a mixed number, divide the numerator by the denominator to get a quotient and a remainder; the quotient is the whole number and the remainder is the numerator over the original denominator.

Example: 121/4 => 30 remainder 1 => 30 1/4
