(two and one fourth) times ten = 22.5

22.5

Start by converting both numbers into improper fractions (common denominator is not necessary). You should get 2 1/4 to be 9/4 and 10 as 10/1. Now just multiply across, meaning numerator times numerator and denominator times denominator. You should get 90/4. Reduce it back into a mixed number to get 22 and two fourths, or 22 and a half.
