Tyrellz Percent Post

What I know About Percent
-out of 100/an equivalent fraction out of 100
-used in a circle graph
-can be used in context
-100 is a number that is just right

-100 percent means everything 100/100 
               40 apples 40/40=100/100
-50 percent means half 1/2  
               50/100 or 25/50
-10 percent means a tenth  
               10/100 or 1/10
-1 percent means... 
               10/100 or 100/1000
25 percent means a quarter 
                 25/100 or 1/4

3. You need to explain how to convert from Decimals to Percents to Fractions.  Choose 3 sets


26%

to find a decimal in a percent you will have to divide the percent by 100. 26÷100=0.26
to find a fraction in a percent you have to just read the decimal. 0.26=26/100

7/10

To convert a fraction into a decimal you will have to divide the numerator by the denominator.              7 ÷ 10=0.7

To convert a fraction you will have to divide the numerator by the denominator 7 ÷ 10=0.7 Then multiply by 100. 7 ÷ 10=0.7 

       0.7÷100=0.007%

0.024
to convert a decimal to a fraction all you have to just read the decimal really. 24\1000
to convert a decimal to a percent you multiply by 100.

4.
180%



















12 3/4
0.7





















20% of 60
60 divided by 100=0.6x20=12
0.1% of 40
40 divided by 100=0.4x0.1=0.4
250% of 400
400/100=4x250=1000

yes i think so because if you add 10%
to 15% you get 25%
