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: [tex]3\ 3/10=3+0.3=3.3[/tex]
Donna's time: [tex]2\ 4/5=2+0.8=2.8[/tex]
Cindy's time: [tex]4\ 3/5=4+0.6=4.6[/tex]
Nicole's time: [tex]2\ 1/10=2+0.1=2.1[/tex]
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:
[tex]4.6-2.1=2.5[/tex] or 2 1/2
