Solution to

Frame 2-36.

Remember " (a + b) (c + d) = ac + ad + bc + bd" from Frame 1-35? This

general formula can be applied to multiplying mixed numbers. For

2

=

example, in the problem 2 1/2 x 3 1/3, let a = 2, b = 1/2, c = 3, and d =

1/3.

7

=

10

= **30**/3

Solve the problem using the algebraic formula, then solve it using

improper fractions. Your answers should be the same.
