I would first translate you minutes into seconds
what is 8 1/3 in seconds and
what is 1 1/5 in seconds
OpenStudy (anonymous):
actually that's not necessary

@GABI_J do you get the question

First turn the fractions into decimals
OpenStudy (anonymous):
and you get .3 repeating, and .2
OpenStudy (anonymous):
yes, I thought it would be easier to translate that in seconds first.....
OpenStudy (anonymous):
so 8.3 repeating *1.2
OpenStudy (anonymous):
9.99999999999999 so lets say 10 minutes

@Loopki40 tis is workin with multiplying fractions
OpenStudy (anonymous):
Ohh then find the lowest common denominater
OpenStudy (mertsj):
Where you wrote "Kate" did you mean Kayla?
OpenStudy (anonymous):
which is 15, so 1/3 = 5/15 and 1/5 = 3/15, then add them to get 8/15

Can you help me work out with a
OpenStudy (anonymous):
Yes @Mertsj
OpenStudy (mertsj):
To find Kayla's time: it is 1 1/5 times as long as Morgan so multiply 8 1/3 by 1 1/5
OpenStudy (mertsj):
morgan is faster because her time is less.
OpenStudy (anonymous):
Is that to find a

Which one asks you to find Kayla's time?
OpenStudy (anonymous):
A
OpenStudy (mertsj):
Then the one that tells you how to find kayla's time is a
OpenStudy (anonymous):
so multiply the 2 numbers to get A
OpenStudy (anonymous):
How do you find b

If one dress costs $10, how much would 3 dresses cost?
OpenStudy (anonymous):
30
OpenStudy (mertsj):
You should say " 3 times 10"
Then you can apply the same thinking:
If 1 mile takes 8 1/3 minutes, how long would 3 miles take?
OpenStudy (anonymous):
So I multiply 8 1/3 with 3
OpenStudy (mertsj):
yes

Can you draw so I can see how to do it
OpenStudy (mertsj):
You mean you don't know how to multiply 8 1/3 by 3?
OpenStudy (anonymous):
Yep to multiply it wouldn't I have to put 3 over 1
OpenStudy (mertsj):
Can you change 8 1/3 to an improper fraction?
OpenStudy (anonymous):
Yes
