What is 0.56 written as a fraction in simplest form?

OpenStudy (hoblos):

to write as fraction you must get rid of the decimal.. so here you have to multiply by 100/100 you get 56/100 do you know how to simplify it ?

OpenStudy (anonymous):

not really

OpenStudy (hoblos):

to simplify you try to divide both the denominator and the numerator by prime number here you can divide by 2 to get 28/50 then also by 2 you get 14/25

What is 3.92 written as a percent? A. 392% B. 39.2% C. 0.392% D. 0.0392%

OpenStudy (anonymous):

3.92 x 100 = ?

OpenStudy (texaschic101):

just move the decimal two spaces to the right and change it to a percent

OpenStudy (anonymous):

3.92 = 392% Remember, 100% = 1, so 300% = 3 and 400% = 4. So, 3.92 must be between 300% and 400%. That tells you where the decimal point goes. ===== Note that "percent" is different from "percentage." A percentage is a fraction of another number, such as "50% of 200 = 100" or "20 is 25% of 80." A percent is a number in its own right. 50% = 1/2. "50% of 200" is the same as "1/2 of 200" is the same as "100."
