help?

Find 40% of £50.

how do you do it, i know the answer is 20 but i wanna know how to get to the answer.

 

Lol, if you dont know simple math just use this; 10% - 5, if you need to get 40% just multiple 10% whatever you need, so 40% = 5(10%) x 4 and you get the answer

 

the way you explained it is confusing :S.

 

Lol, thats the most simple way to do it. Lets say you got numer of 100, you need to get 40% off 100, all you do is get the 10% which is 10, then you just multipe it by 4 and you get 40 which is 40%. The most simple way, 10year kids use this, lol.

 

i get it but the way you say it is confusing..

 

Maybe it is better explained like this... Percent is exactly what it sounds like -> Per (out of) cent (100). So 40% is 40 / 100. When you do 40% of £50 it would be doing this:



The other way to do this is to go back to what I said earlier (definition of percent).

40%, you move your decimal two places to the left. So 40.% of £50 = .40 x £50

If you have a smaller number you still move two places to the left.
ie: 5% x £50 = 0.05 x £50

Hope something from here helped.

 

i'm calling troll right now

 

50 * .4 = Answer

 

You can find 10% of 50 -> 50/10 = 5
Then you know 40 is 4*10. So do 5*4.
