Percentages

[pb100191]

I'm completely confused about percentages. How would you make a fraction into a percentage. For example; 70/180.. what is that into a percntage (How do you make it into a percentage).

And, if a car costs �12,000 and you needed to put on the VAT of 17.5% how much would it cost? V confusing for me....

For the first one, divide the 70 by 180 and then multiply by 100 to give a percentage.

For the second one, divide the percentage by 100 (to give 0.175) and then multiply this by �12,000 to give the VAT which you must then add on to the �12,000.

It is easier just to multiply 12,000 by 1.175 to get the final figure but you may not understand why you are doing this

Hi pb100191

percentage % means 'out of every hundred' that's why you devide/multiply by 100.

to find the % of a fraction for example 70/180 you basicly want to to find X in (70/180 = X/100)
X = 70/180 multiply by 100)

you can visit the following site for some explanation:

Do you have Excel on your computer

If so open Excel and in any cell put =70/180*100 and you will get your answer
