how do you take 15% from 4,000

Question

What formula would I use? I'm just trying to figure those two numbers and every time I try to search it on Google it gives me a list of sites that only give me a formula that involves me providing more than two numbers. Example of one formula they provided is FV=p(1+r over n)nt. (Note: r is supposed to be over n as in like fraction form but my phone won't do fraction form) (note: nt is supposed to be in exponent form) Please help this is very frustrating and I'm only in 6h grade they haven't taught us that in school yet at least not in my district they slow on teaching us

Answer 1

If you want 15% of 4000 then the question is "what is 15% of 4000?"

"what" means x

"is" means =

"%" means /100

"of" means *

x = 15/100 * 4000

x = 600

Answer:  600 is 15% of 4000.

.

If the question is "what is left if you take 15% from 4000?" then:

Whatever you start with is 100% of itself.  If you take 15% away, then you have (100-15)% = 85% left.

Asking "what's left if you take 15% away" is the same thing as asking "what is 85% of"

What is 85% of 4000?

x = 85/100 * 4000

x = 3400

Answer:  If you take 15% away from 4000, you have 3400 left.
