let see you divided both sides by 0.05 giving you 100=P*(1/100)(1/2) 100=P*(1/200) 2000=P by multiplying 200 on both sides
still kinda lost sorry
or what would problom look like when divied
do you know .01=1/100?
Examples: 1/10=.1, 1/100=.01, 1/1000, .001, 1/10000=.0001 so on....
yea i know that
ok do you know how to multiply 1/100 * 1/2
to multiply fractions you multiply straight across on the numerator and then for the denominator like I did above
Since we are trying to get P by itself and it is being multiplied by that 1/200 to undo this multiplication we multiply by the multiplicative inverse of 1/200 to get the multiplicative identity 1. The multiplicative inverse of 1/200 is just its reciprocal which is 200. So we multiplied by 200 to get the multiplicative identity. The multiplicative identity times any number will be that number since the multiplicative identity is 1. But since we multiply 200 on one side we have to do it to the other side of the equation
nope thanks alot
really you're good?
isn't the word multiplicative cool?
say yes. you know you want to
i had the hardest time saying that word, and I finally got it. I used to couldn't say it
lol well not really i man i kinda get the problem but i mean
I like to change everything to fractions, but you could have left it "deciamly"
yea i show you next problem and then show you what i think then can maybe walk me throw it lol like i have done others on here before lol
i will show you problem
k bring it
i know that the fraction will be 3/4
because 9/12=0.075 wich is 3/4 in fraction
are you talking about your P is 3/4? If so, then thats incorrect
so i will take 0.04 (3/4)
becasue be 9 /12
Our formula for interest is I=Prt where r=4% and t=9 and I=42 and they ask us to solve for P. Let me see you plug those in
okay give me sec
I=42,r=0.04,and t=9/12=3/4 thats what i got so far
and in terms i will have
I=prt 42=(0.04)(3/4) 42=P(0.03) then how will i caculate to get P
I thought t=9? let me look again
t=9 not 3/4
i will show you an exapmle it gives me how to do problem
but say's got to divide 9 by 12 months
oh i didnt see the month thing sorry
yes there are 12 months so the time will be 9/12 gj
wich means will be 0.075 in dec and 3/4 in fraction
I=prt 42=(0.04)(3/4) 42=P(0.03) do i got to divide the 0.04 and (3/4)
yes so far correct
but if i divide i will get 0.05
if i divide 0.04 and 3/4
get 0.05 right
since we should be multiplying those we get .03
all i get it
now thats so crazy lol
then i take 0.03/42 and that =P
i mean *
thats crazy i been working on problem couple days and all i need to do lol
i knew how to work problem
thanks for all your help man thanks alot
maybe can help me with couple more
i wirked on i got most of problem but can figure certin ones out
parts of them
like i get 33.25 ______ 1900 (3/13) make r=
yes looks good
the first one does. did you want me to check the other two or something?
what was your strategy for the next one?
the frist two are good what i am having trouble with is the intrest rate
what is the formula for actual interest?
i know how to do problem but like when i divide then top by botton and add the bottem times ther fraction not sure i am doing ti right
i will bbl maybe
