any1 know how to find the amount of the variable when working with percents using 6th grade math?
an example might be useful to work with
364 is what percent of 455
1 percent is equal to a division by 100 1% of 455 = 455/100 how many 1% are in 364? divide 364 by the value of 1%
all i need to know is how to set the problem up. my teacher told us that we need to use cross multipling
btw this is mt h/w that i cant figure out
divide 364 by some unknown value: x and equate it to that 455/100 \[\frac{364}{x}=\frac{455}{100}\] that works out to the same thing .... just solve for x
exactly what i need to know
there are actually a number of different ways to set up that same problem ... \[\frac{364}{x}=\frac{455}{100}\] \[\frac{364}{455}=\frac{x}{100}\] \[\frac{100}{455}=\frac{x}{364}\] \[\frac{100}{x}=\frac{455}{364}\] all of these would produce the same result
the second one is prolly the "correct" setup if you want to go by how textbooks do it
we dont use textbooks in my class
100 times ? is 100? and 364 times 100 is 36400 then i have to divide
? is the variable
so it would be|dw:1381959422481:dw|
