Every percent can be changed into a decimal or fraction. The problem 20% of 10 is a multiplication problem because you want something of something. Note: 20% = 0.20 = 20/100 = 1/5
0.20 x 10 = 2 revisit the rule for multiplying decimal or
20/ 100 x 10 / 1 = 200/100 = 2 revisit the rule for multiplying fractions or
diagram 10 divided into 5 parts which have 2 in each equal part.
To solve this problem you set up a ratio. We read the question as: "what is 20 percent of 10?" The ratio looks like the following:
20/100 = x/10
Next, you cross multiply:
20*10 = 100*x
this gives us:
100x = 200
dividing both sides by 100 we get
x=2
Thus, 2 is 20% of 10.
Simple English: (how to work out a percentage of something).
100% means everything. I put in 100% when I ran a race. I put in everything when I ran a race.
To work out a percentage of anything you need to first divide the number by 100.
So if you had to work out 20% of 10 you would take 20 and divide it by 100.
Then you would times it by 10 which gives you the answer of 2.
Another way to look at this is to translate the sentence "What is 20% of 10?" to (n) = .20 * 10. When you multiply 10 and .20 you get 2, so n=2.
