38 is 0.2% or 0.002 of the total no of people voting.

Thus the number of people who voted is 38/0.002 = 19,000

a million. One huge form is x, the different one is x - 6. So, x^2 + (x -6)^2 = 146 x^2 + (x -6)(x -6) = 146 x^2 + (x^2 -12x +36) = 146 x^2 + x^2 -12x +36 = 146 2x^2 -12x +36 -146 = 0 Subtract 146 from both area 2x^2 -12x -one hundred and ten = 0 Divide both area by ability of two to get x^2 -6x -55 = 0 ingredient (x - 11)(x + 5) = 0 x = 11 and x - 6 = 5. both solutions are 5 and 11 or x = -5 and x - 6 = -11. both solutions are -5 and -11 some thing looks incorrect with huge form 2. If W = x and L = x -5, then the dimensions is decrease than the width that's unconventional.

1% is the same as saying 1/100.
Therefore 0.2% is the same as 0.2/100

You can multiply anything by 1 without changing it.

5/5 is the same as 1.

multiply 0.2/100 by 5/5 to get 1/500

So, we have shown that 0.2% is the same as 1/500

You are looking for a number x. You do not know what x is, but you know that if you divide x by 500, you get 38.

Therefore, x must be 38 times 500 = 19,000

I'm surprised that Mr. Mouse got so few votes..

38 = 0.2% ... [ 38 = .02/100] so(multiply by 100)
3800= 0.2 (now multiply by 50)
19,000=1 ... 19,000 voted

38/19000= ? (it better be .002)

let X=the total number of people who voted.
38 is the number that voted for Mickey.
38 = .2% 38=.2/100 (The definition of percent) of X

.2/100 * X = 38
100 * (.2/100 * X) = 100* 38
.2*X=3800
10 * (.2*X) = 10*3800
2*X = 38000
(2 * X) /2 = 38000 /2
X=19000

0.2% of X = 38
0.002 x = 38
x = 38 / 0.002 = 19000

its like:

0.2% of x = 38
or, 0.2/100 * x = 38
or, x= (38*100)/0.2 = 19000.

thats all

let the total number of voters be Y
0.2% voted for Mickey Mouse = 38 voters
0.2% of Y = 38
0.2 * Y / 100 = 38
Y = 38 * 100 / 0.2 = 19000

38 people represents 0.2% of the population that voted for Mickey Mouse, then there would be a total of 19,000 people that voted in this election.
