Solution to

Frame 2-4.

When you divide a fraction by another fraction, invert (flip) the second

fraction and multiply the fractions.

a. 1

b. 3

4

For example:

2

c. 14

d. 6

To solve the problem 1/2 1/4 (one-half divided by one-fourth), you

would invert the (choose one -- 1/2; 1/4) and multiply.

6 asks, "How many groups of 6 are in 18?", so

NOTE: Just like 18

1/2 1/4 asks, "How many one-fourths are in one-half?" (or, "How many

quarters are in a half?").

a. 1/4

1/4 =

1/2

1/6 =

b. 1/2

1/2 x 4/1 = 4/2 = 2

(There are two quarters in a

half)

2/3 =

d. 3/7

Solution to

Frame 2-6.

someone say, "You can't add apples and oranges"? Well, there is a

a. 2

b.

6

similar rule when working with fractions -- you can't add fractions with

4

2

different denominators.

c. 14

d. 9

This means that, in order for two fractions to be added together, the

9

14

numbers must be the same.
