Percentages have confused everyone at some point in their lives. In actual fact, they’re quite simple. The process of calculating a percentage is just working something out ‘out of 100’. The actual symbol for percentage (%) is mathematical jargon that means ‘out of 100’. There are many taught ways to calculate percentages and some percentages are easier to work out than others.
Firstly, the basics: 50% is half of the thing (Jenny and Jim sliced the pie in half and each had 50%)
25% is a quarter, half of a half (Jenny and Jim sliced the second pie into four quarters, making each slice worth 25% of the whole thing),75% is three quarters (25 x 3 = 75) (Greg stole three slices of the second pie, which was 75%)
And finally, 100% is the whole. The entirety of the figure/object. (Jim had gone home when Jenny’s last pie was finished. She had the whole 100% of it to herself).
To work out 10% of something, simply divide the initial figure by 10. For example: To calculate 10% of 365, work out 365 ÷ 10 which is 36.5 (if dividing by 10, simply move the decimal point one figure to the left). By taking this 10% figure you can then work out any of the percentages that end in 5 or 0. 20% = 10% x 2 and 5% = 10% ÷ 2
For a more precise percentage such as 46%, if you are not fussed about being precise, simply work out 50% (half) and subtract an extra little bit. If you need to be precise, then the easiest way to work out 46% is to find what 1% is. Divide your initial figure by 100 (simply move the decimal point two steps to the left and voila, 1%), then multiply that by the percentage figure you desire.For example: You wish to know 46% of 56. Step 1: 56 ÷ 100 =0.56. Step 2: 0.56 x 46 = 25.76. 46% of 56 = 25.76
16 is 40% of what number?
Percent is an abbreviation for the Latin word 'per centum' which means 'for every 100.' 15 percent means 15 out of every hundred. To find percentage of a certain number, divide the given amount by the total amount and multiply the answer by 100. For instance, if you get 40 marks out of 50, the percentage is 80. 40/50x100=80 percent.
To change percentage into numbers, divide the number by 100 and multiply by the total number. For instance, if you have scored 80 percent and want to know what your score is, out of the total marks of 60, you have to do this: 80/100x50=40
(X / Y)*100 = Z
Where X=Given amound
Z=Answer in %
eg: You have got 45 mark in an exam out of 50. Then your percentage is 90
(45/50)*100= 90 %
The easiest way to calculate a percentage to me is to take the percentage turn it into a decimal and multiply.
1% of 321
1%=.01 so just multiply .01 by 321 and you will get the ammount
.01 times 321 = 3.21
Therefore 1% of 321 is 3.21
Hope I helped!!
You divide what it is out of and what you got then times that by 100 the numbers you get before the decimal is the percentage
