how do you do like a problem like:

30% of 45?

30% of 45?

#2

45 * .3

.3 is 30 % of 1, so yeah.... if you don't get it, then wake up in school

EDIT: the answer is 13.5, btw

13.5

Hth

Hth

#4

Put the percent in decimal form and multiply like 45 x .30

#5

You could just google that question and it answers it for you.

Not good come exam time, but good in the short term.

set up a proportion.

30% of 40 is really 30/100 = X/40 (30/100 is 30 percent as a fraction).

Now, cross multiply. 30x40/100. You can then plug that answer into the Numerator spot of your x/40 fraction.

Hopefully that makes sense enough for you.

It makes be sad that I know what you're talking about.

#12

if 45 is 100%

1% = 45/100

45/100 * 30

voila, answer

1% = 45/100

45/100 * 30

voila, answer

#13

You guys over complicate these problems, just 45 x .3 is enough.

#14

Hmmmm....rule of three?

k... so this post has nothing to do with your question but gonzaw you deff got me with the black UG skin... god damn you... ( i swear i don't highlight ppls posts )

I haven't heard it pronounced this way until I started coming on to UG. We Americans spell and say things way too differently

#16

What those guys say.

Or non calculator,10%=45/10=4.5

30%=4.5*3=13.5

Or non calculator,10%=45/10=4.5

30%=4.5*3=13.5

You're in what, second grade?

Here's a better math problem. What's 1/0?

thanks a lot. my brain hurts now

#19

I didn't know there were 6th graders on UG. >_>

#20

k... so this post has nothing to do with your question but gonzaw you deff got me with the black UG skin... god damn you...( i swear i don't highlight ppls posts )

Then how could you be sure that what I wrote wasn't seen in UG Classic?

Maybe if you changed to UG Classic, I would follow you and edit the sig out before you saw it, but since you are so sure:

first, multiply 45 times 10,000. this will give you a huge number.

then, multiply the other percent by 100. this will give you a fairly large number.

examine the numbers. then proceed to divide both numbers by 2. this will give you half of what you had before in the category of both numbers. you would then multiply the two numbers. then, take the number that results from that multiplication and multiply it by four. then, divide this number by 10,000. then divide this number by 1000. the answer, inexplicably, will be the correct answer. works every time.

Or just do 0.3*45.

TS, you're like almost 15 and can't do this?

Clearly Yakult has given the threadstarter a hint through this statement.

Let's look at this very carefully.

"DAMN YOU AMPERE"

Why damn Ampere? It's obviously a sign. We must start with an Ampere, yet the unit is unruly for normal math.

So,

1 Ampere = 1 coulomb per second

1 coulomb = 96,485 Faradays

We now have:

96,485 Faradays per second

Now refer to the equation

If you plug in the constants and the 96,485 Faradays we calculated you get

7148.148148.

Divide the original amount of Faradays by your answer and you get the final answer.

96,485 / 7148.148148 = 13.5

All of the units cancel out so you are left with the number only.

Of course, this is only without the presence of Magnetic Monopoles, with them and you must convert to imaginary numbers.

It's quite simple, really.
