Question
I am not being lazy, I've tried to get this done several times, but I am VERY bad when it comes to fractions.
Barbara, Donna, Cindy, and Nicole ran in a relay race.
Barbara: 3 3/10
Donna: 2 4/5
Cindy: 3 2/5
Nicole: 2 1/10
1. The four girls ran in a relay race as a team. If each girl ran one part of the race, what was the team's total time?
2. Find the difference between the fastest girl's time and the slowest girl's time.
3. To break the school's record. the girls' time had to be faster than 12 2/5 minutes. Did the girls break the record? If so, how much faster were they? If not, how much slower were they?
--------------------------------
This is the same as the first one but with different people and times.
James: 2/3
Gilbert: 11/12
Matthew: 5/6
Simon: 7/12
4. The four boys ran in a relay race as a team. If each boy ran one part of the race, what was the team's total time?
5. Find the difference between the fastest boy's time and the slowest boy's time.
3. To break the school's record. The boy's time had to be faster than 2 7/12 minutes. Did the boys break the record? If so, how fast were they? If not, how much slower were they?

Click on Numbers. Then click on Fractions Menu.
Study this section carefully, including the explanations and the how-to examples.
What you need for these problems are the explanations for <b>adding</b> and <b>subtracting</b> fractions.
"what was the team's total time" = add
"Find the difference" = subtract
"Did the girls [boys] break the record?" = adding or subtracting depending on their time compared to the record time.

To me the two questions are the same.
What difference doe their names make??
The second is easier than the first, since it does not contain mixed fractions.
So let's start with the first one:
Step1 : get rid of those non-workable mixed fractions.
3 3/10 = 33/10
etc
1. for the first part you are now going to add those 4 fractions, after you found the LCD, which would be 10
2. Subtract the smallest fraction from the largest fraction.
3. The record is 12 2/5 minutes or 62/5 minutes.
Take the difference between 62/5 and the sum you got in the first part, then draw you conclusion.
Repeat those steps for the second question.

Looks like I can't make up my mind if it should be:
What difference do their names make??
or
What difference does their names make??

Did someone find the answer to this problem?
yes
i know im stuck on it too
emma
this is my school work but when I get the answer I will post it :)
phantom of the opera
yea same i will tell you guys the answer when i get my work done this is part of my homework you have to wait for 2 or 3 days
hi
um you never told us phantom of the opera
