Write the fraction as a percent. If necessary, round to the nearest tenth of a percent. 5 2/5 A. 540% B. 5.4% C. 5.38% D. 534%

OpenStudy (anonymous):

write the fraction in words. ex. 1 1/2 would be one and one half

OpenStudy (meilendurcer):

5.4?

OpenStudy (anonymous):

@meilendurcer do you understand how? or do you want me to help you do it?

OpenStudy (meilendurcer):

help me with it

OpenStudy (anonymous):

in words. You would write it as five and two fifths. You just write it as you would pronounce it.

OpenStudy (anonymous):

Anything to the left side of the "and" is a whole number. Anything to the right side of the "and" is a decimal.

OpenStudy (meilendurcer):

Ok i get it so far

OpenStudy (anonymous):

So, you have 5 as a whole number and 2/5 as a decimal. To get 2/5 as a decimal, you divide 2/5. You should get 0.4

OpenStudy (anonymous):

okay?

OpenStudy (meilendurcer):

i did

OpenStudy (anonymous):

now solve 0.4/100 because you want it to be a percent

OpenStudy (anonymous):

what do you get when you solve 0.4/100 (you can use a calculator)

OpenStudy (meilendurcer):

0.004

OpenStudy (anonymous):

Now move the decimal two places to the right

OpenStudy (anonymous):

(it's not always the number you start with haha)

OpenStudy (anonymous):

I was showing you the full steps. You should get .4 again, and that equals 40%

OpenStudy (anonymous):

WAIT NOT 40% its 4% sorry typo

OpenStudy (anonymous):

so since your whole number is 5 and you now have 0.4, combine them to get......?

OpenStudy (anonymous):

5.4% because you add 5 to .4 and you get 5.4%! okay? Do you want me to cover anything else?
