Xelga [282]

Answer: 2.5 or 2 1/2

Step-by-step explanation:

You can convert the mixed fractions to decimal numbers:

- Divide the numerator by the denominator of the fraction.

- Add the result to the whole number.

Thenyou have:

Barbara's time: 3\ 3/10=3+0.3=3.3

Donna's time: 2\ 4/5=2+0.8=2.8

Cindy's time: 4\ 3/5=4+0.6=4.6

Nicole's time: 2\ 1/10=2+0.1=2.1

As you can see, the fastest girl is Cindy and the slowest girl is Nicole.

Then, you must make the following subtraction to calculate the difference:

4.6-2.1=2.5 or 2 1/2
