## lexiamee Group Title how to simplify proportions and ratios one year ago one year ago

example?????

2. lexiamee Group Title

well 25 to 15 would that be 5 to 3

yes correct.

4. lexiamee Group Title

thanks... what about 7 over 14x

$\frac{7}{14x}$

6. lexiamee Group Title

yes

just think about normally trying to break down fractions.

7/14 = ?

We can also plug in for x.

10. lexiamee Group Title

2

$\frac{7}{14 * 2}$

7/14 isn't 2.

13. lexiamee Group Title

1/2

yes, correct. Now what is $\frac{7}{14 * 2}$

15. lexiamee Group Title

4

16. lexiamee Group Title

noooo hold on 1/4

then solve $\frac{1}{2 * 2}$

18. lexiamee Group Title

so 1/4

just remember if it's a bigger # on the bottom, then the bigger number stays.

there.

also remembe you can plug in any number to solve. As we see by plugging in 2 we get the same answer both ways.

remember also that simplifying techniques are the same all over, just need to know the situations. Ratios, as above can be tricky if you dont' think about it.

how would I solve 4xy over 0.25x

are you making this one up?

or is it a legit Q?

26. lexiamee Group Title

no it is one of my questions for work.

I guess we woudl just cancel out.

$\frac{4xy}{0.25x}$ $\frac{4y}{0.25}$

always important to see what is in both denom and numerator. Cancelling is HUGE later on in math.

now how many times does 0.25 go into 4?

31. lexiamee Group Title

idk

....... count it out. what's .25 x 2?

33. lexiamee Group Title

.25*2= .50

yup, nowhow much is 4?

0.25 x # = 4????

or now that you know 0.5 you could do 0.5 x # = 4? then double it.

37. lexiamee Group Title

im lost sorry

okay.... 0.25 x 2 = 0.50 0.25 x # = 4???? (0.25 x 2 = 0.50) x # = 4??

how many times does 0.25 go into 4....

nevermind thank you
