+1011 When you are finding a percent do you always multiply say like what is 20% off 80 what would it be??
+128474 Note, Nickolas, that 20% off is the same thing as 80% of something = .80 ...so....
.80 * 80 = 64
Another way is to take 20% of 80 = .20 * 80 = 16
Then....subtract this from 80 =
80 - 16 = 64 !!!
+434 What I some times so if its a percent like 1 out of 100 I didvide the number by 100 then multily the quiotent by the percent
+1011 Wow that is simple so here is one I would like to try and make sure with you it is correct
+434 Sure. But remember this dosen't work for like finiding 3.4 percent of a number just any whole number from 1-100
+1011 Every time I try your way CPhill the numbers go in the 100000
like
40 take away 20%
I do 40*40 = 1600
+128474 Remember that we need to convert the % to a decimal
To do this....drop the % sign.....move the decimal two places to the left
So....for instance
20% = 20.% = .20
So
20% of 45 =
20.% * 45 =
.20 * 45 =
9
+128474 60.....take away 20%
20% = .20
So
.20 * 60 = 12
Take 12 away from 60 =
60 - 12 =
48
+1011 To me it is changing I have not got one right it keeps changing the way it is multiplied to
+128474 Ok...let's forget the decimals and write 20% as 20/100
So
(20 /100) * 60 = 1200 / 100 = 12
Take this away from 60 and we get
60 - 12 =
48
Is that a little easier for you???
+434 Thanks it isn't math and it sounds cheeky but how long have you been doing the on your question kind of curious for my math forum history guide sounds weird but I'm making one XD
