well she wants to make a dozen towels. a dozen is 12 so she wants 12 towels. each towel is 3/4 yards. so we can add 3/4 12 times like
3/4 + 3/4 + 3/4 and so on. or we can do
12 * 3/4
we can rewrite 12 as 12/1. like this
12/1 * 3/4
to multiply fractions we multiply the tops and get
12 * 3 = 36
and then bottoms
1 * 4 = 4
we put top over bottom
36/4
simplify
9/1 = 9 yards
