### Larrisa's scribepost for Percents

HI EVERYBODY (:

Key Ideas :

Fractions, Decimals and percent can be used to represent numbers in various situations.

Percent can be written as fractions and as decimals :

examples : 1/2 % = 0.5%/100 = 0.005

150% = 150/100= 1.5 or 1/2
42 3/4% = 42.75% 42.75% = 42.75/100 = 0.4275

Show you know :

fraction to decimal to percent :

3/40 = 0.0075 = 75%
171/300 = 0.57 = 57%
88/50 = 1.76 = 176%

decimal to percent to fraction

0.0064x100 = 0.64%
0.64 x 100
-----
1000x 100

= 64 divide by 2 / 10 0000 divide by 2

32 /5000

16 /2500

8 /1250

percent to decimal to fraction:

750% 7.5 7 50/100 7 1/2
0.3 divided by 100 0.003 / 1000 3/100
12 3/4 divided by 100 1275 divided by 100 = 0.1275/ 1000 1275/1000 51=400

Good job Larrisa. You blog was kind of boring because it didn't have any pictures and it was so simple. But you explained everything well and clearly. Maybe next time you should put pictures.

Good job again!!
