easy, any time you have a fraction it's the same thing as a division problem.. so 20 out of 30 is the same thing as 20/30 or 20 divided by 30... of course when you divide 20 by 30 you'll get a number smaller than 1 so just multiply by 100 or move the decimal 2 places to the right

20/30, then take your answer x 100.
When you divide the fraction, you will get a decimal. To convert a decimal to a fraction, you can think of it 2 ways: (1) multiply the decimal times 100, or (2) move the decimal 2 place values to the right.
Have fun!

I was taught the rule
is/ of
soooooo
20/30 x/100
cris cross and multiply...
20 x 100 = 2,000
Then divide by the remaining number...
2,000 Divided by 30 = 66.67
so bascially rounded its 67%
* remember if the problem says what IS 20 our OF 30
remember is over of and the other is blank on top of 100.... for 100% ...
Works everytime

20/30 x 100% = 67%

20 divided by 30 gives 0.6666... (repeating), so the percentage is 66.666... %, or 66 2/3 %
If you round-off a number, you change its value. So saying "67%" or "66.67%" or "66.6666667%" are all incorrect. They're just approximations.

66.66666666....%. 20 / 30 is 1 / 3 which is that percentage.
