What base? ..... So, we're saying x*0.0075 = 36. Can you solve for x?
OpenStudy (anonymous):
yes solving for x. how come you moved the decimal point?
OpenStudy (ipwnbunnies):
It's just a way of writing a percent when doing a problem. For example, we want to 50% of 10. Would you agree 50% of 10 is 5?
OpenStudy (ipwnbunnies):
want to find*
OpenStudy (anonymous):
well yes 5 is 50%. but that doesn't explain why you moved the decimal point. I just tried it on my homework and 36 isn't right.

Are you aware that 1%=0.01
OpenStudy (kc_kennylau):
Or 100%=1
OpenStudy (kc_kennylau):
That's why 0.75%=0.0075
OpenStudy (ipwnbunnies):
Stay with me lol. If we wrote it out in a problem, it'll be 10 * 0.5 = 5. For percents, move the decimel 2 spaces to the left.

So you're asked to find 36 is 0.75% of 'what'

That means 0.75% of 'what' is 36
OpenStudy (kc_kennylau):
Or 0.75%\(\times\)'what'=36
OpenStudy (kc_kennylau):
Which is the same as 0.0075'what'=36
OpenStudy (kc_kennylau):
Get it?
OpenStudy (anonymous):
yes that makes sense! Thank you for explaining all of that! I really appreciate it
