Answer 6

Do you know about proportions? Or how to make them, and solve them? (:

Answer 7

im pretty bad at them T.T

Answer 8

Ok, they have given us three pieces of informations, and they want us to find the fourth piece.

Answer 9

So they gave us this:

2 2/5 minutes to run 1 1/2 miles
????? minutes to run 1 mile

Answer 10

soo do we divide 2 2/5 by 1 1/2?

Answer 11

Well, first lets simplify 2 2/5

That equals to 7/5
and 1 1/2 = 3/2

So lets rewrite what they gave us so far :)

7/5 minutes to run 3/2miles
????? minutes to run 1 mile

Answer 12

So make a proportion out of that:

\(\sf\Huge\frac{\frac{7}{5}~mins}{\frac{3}{2}~mi}=\frac{??~mins}{1~mile}\)

Answer 13

\[\frac{ 14 }{ 10 }\div \frac{ 15 }{ 10 }?\]

Answer 14

can u simplify it like that?

Answer 15

yes, you can :)

Answer 16

\[\sf\frac{ 14 }{ 10 }\div \frac{ 15 }{ 10 }=\frac{14}{10}\times\frac{10}{15}\]

Answer 17

\[\frac{ 140 }{ 150 }\]

Answer 18

And you can remove the extra zeros so you are left with

\(\sf\Large\frac{14}{15}\)

Answer 19

So now we have

\(\sf\Huge\frac{14}{15}=\frac{??}{1}\)

Answer 20

So do you know how to cross multiply?

\(\sf\Large\frac{a}{b} = \frac{c}{d}\to ad=bc\)

Answer 21

dis is de part where i get all confused ?.?

Answer 22

oh yeh i do

Answer 23

14x1=15x

Answer 24

So this is what we have so far:

\(\sf\Huge\frac{14}{15}=\frac{??}{1}\)

This is what we need to use to solve it:
\(\sf\Large\frac{a}{b} = \frac{c}{d}\to ad=bc\)

Answer 25

so 14=15x?

Answer 26

exactly, and now just divide 15 on both sides! :)

Answer 27

k so so x=14/15

Answer 28

and 14/15=0.93... T.T

Answer 29

Correct, but I think they would just want the final answer in fraction. So just 14/15.

Answer 30

crud, thats not even part of the answers T.T

Answer 31

Oops, I made a mistake :/

\(\color{blue}{\text{End of Quote}}\)

2 2/5 = 12/5

Answer 33

O.O THESMARTONE MADE A MISTAKE, IS THE WORLD ENDING!?!

Answer 34

So make a proportion out of that:

\(\sf\Huge\frac{\frac{12}{5}~mins}{\frac{3}{2}~mi}=\frac{??~mins}{1~mile}\)

Answer 35

idk how to make proportions out of fractions T.T (im pretty new to them)

Answer 36

Basically, keep the units the same.

So you have minutes over miles on one side. And minutes over miles on the other side :)

Answer 37

i dont get it, isnt that how it is right now? ?.?

Answer 38

That is how you make i a proportion and that is how it is right now. :)

remember it should have the same units on both sides.

Answer 39

ok so... wut about the fraction parts?

Answer 40

Lets simplify it :)

\(\sf\Huge\frac{\frac{12}{5}\times \frac{2}{3}}{\frac{3}{2} \times \frac{2}{3}}=\frac{??~mins}{1~mile}\)

Answer 41

k gimme a sec to solve this

Answer 42

1 3/5 over 1?

Answer 43

correct :)

Answer 44

OH SO THE ANSWER IS 1 3/5 THX!

Answer 45

Correct :D
