well i know that proportion is showing 2 equal ratios

- KatrinaKaif

Use what I taught you.

- Hero

Katrina taught somebody something?

- anonymous

75 of n=66 75x66=n

- anonymous

I find Katrina very clear

- KatrinaKaif

Come on star, break this down as I taught you too.

- Hero

is/of = %/100
66/x = 75/100

- anonymous

hmm..
66/75 = 0.88
0.88 * 100 = 88

- KatrinaKaif

75% converts to?

- KatrinaKaif

.75

- anonymous

Guys wait you are all confusing star

- Hero

66/x = 3/4

- KatrinaKaif

I guess Hero wants to explain. He shall assist you.

- anonymous

Did I explain it properly?

- Hero

Don't look at anyone else's steps, just look at mine :P

- anonymous

, 75 and 66 is .66 so

- KatrinaKaif

66 remains 66 because it is not 66%.
If it was a percentage, then you will use the decimal.

- anonymous

ok

- Hero

It says to use a proportion. I provided the proper set up for this.

- KatrinaKaif

Well then, provide the steps and help her.

- Hero

I did

- anonymous

wait can u write all the steps down so i can write it down and study it

- anonymous

so i can memorize

- KatrinaKaif

Don't memorize Mathematics. Comprehend it.

- anonymous

well teach me hero

- anonymous

Katrina is correct =)

- KatrinaKaif

as always =P

- Hero

The question asks:
75% of what number is 66?
is/of = %/100
66/x = 75/100
66/x = 3/4
3*x = 66*4
3x = 264
x = 264/3
x = 88
Therefore, 75% of 88 is 66
Pippa, this truly is the proper solution given what is asked of the original question.
Proportion is an equation with the form:
a/b = c/d

24 is 96% of what number?

- anonymous

go

- Hero

I'm going to bed. I'm not doing this again, lol

- anonymous

pippa can u explan it step by step?

- KatrinaKaif

Star, try first.

- anonymous

ok well 24n=96% and 96/n=24 so 96/24=4and244=96% so the answer is 6% of 96%

- anonymous

is that correct?

- anonymous

correction 24 is 6% of 96%

- KatrinaKaif

Star...

- anonymous

wat is it wrong agian?

- KatrinaKaif

24 is 96% of what number?
What is your expression here?

- anonymous

24 is n of 96

- anonymous

i thought i was right!!??

- KatrinaKaif

96% converts to what?

- anonymous

.96

- KatrinaKaif

Good, so now your eequation is:
24 is n of .96

- KatrinaKaif

"Is" converts to?

- anonymous

um =

- anonymous

%

- KatrinaKaif

Great.
Now our equation is:
24 = n of .96

- KatrinaKaif

What does "of" convert to?

- anonymous

%

- KatrinaKaif

What does OF convert to Star?

- anonymous

%

- KatrinaKaif

"OF" does NOT convert to a percentage sign!!!

- KatrinaKaif

Scroll up, view and refer to your past questions and my explanations on them!!!

- anonymous

x

- KatrinaKaif

Multiplication.
Now our eqaution is??

- anonymous

no i put x in cuz i meant mutliplycation i did not know how to put it

- KatrinaKaif

Now, we found all our components.
Our equation is?

- anonymous

our equation is 24=n *.96

- anonymous

i think thats times

- KatrinaKaif

Yay! Good!

- KatrinaKaif

Now lets solve.
24 = n x .96
The "n x .96" can be easily written as ".96n"
Do you understand why?

- anonymous

yes cuz when there togeter like that it is *(multiplycation)

- KatrinaKaif

Good!!
So our final equation is:
24 = .96n
How can we get "n" alone?

- anonymous

24 is 48% of 96%

- KatrinaKaif

Answer my question..the answer you got is inaccurate.

- anonymous

wat do u mean?

- KatrinaKaif

24 = .96n
Our goal is to get "n" alone.
To do so, we have to divide .96 from both sides
When we do so, we get:
24/.96 = .96n/.96
.96n / .96 gives us simply "n"
24/.96 give us?

- anonymous

n=50%

- KatrinaKaif

24 divided by .96 is???

- anonymous

25

- KatrinaKaif

Do you understand how to do this whole thing?

- anonymous

yea just about thank u

- KatrinaKaif

Anytime =)

- KatrinaKaif

25 is correct by the by
