3 1/3 x 2 2/5
(HINT: mixed numbers are fancy improper fractions)
first turn the mixed numbers into improper fractions
3 1/3 = 3 x 3 + 1 = 10/3
2 2/5 = 5 x 2 + 2 = 12/5
Multiply the improper fractions
10/3 x 12/ 5 = 120/15 = 8
What is the diameter of the Earth?
(how wide is the Earth at the equator)

3 3/5 ÷ 2 1/2
Turn BOTH into improper fractions
3 3/5 = 5 x 3 + 3 = 18/5
2 1/2 = 2 x 2 + 1 = 5/2
Restate the equation using KCF
18/5 x 2/5 = 36/25
Turn the improper fraction into a mixed number
36/25 = 1 11/25
1867
When do we pack up our things and end class?
