you can always use:

(part/total)x100

(225/2250)x100=10

O i get it now hahaha

Dragon were you talking to me? My english is bad so please make it a bit more easy :)

The answer to the one that's wrong is: 12x(x-11) = 12x^2 - 132x = x(12x-132) but that last step isn't necesary

if in the test was: 12x(x-11)=0, you also have to say:

x=0 v x=12x-132

x=0 v 12x=-132

x=0 v x=-11

What you need to do is multiply the number which is in front of the ( & ) with that what is in it, -12y(y-6):

Multiply y with -12y, that's -12y^2. muliply -6 with -12y that's 72y (negatif x negatif is positif), so -12y^2 + 72y and than futher as has been shown in the past answers

Life is a biologic thing, something is alive if it breaths, and a couple more things, see google.

Now stop asking questions like what is maths, what is life that's not what this forum is ment for.

Indeed, it's not a secret!

Fun thing to know: Over here, in the Netherlands, it's twenty past 3 PM!

You can also use procents, 1/5 is in procents 20% and then you use ([amount]/100)*[procent]

If it's to hard to make a procent, you can just divide the amount by the most down number of the fracture, but you can only do this if the upper number is 1.

You can always use [amount] / 100 (now you know 1%) * [procent] (nine in this example).

So: (1000/100)*9= $90
