if x is r percent of y and if k is s percent y, then x is what percent of k?

100(r+s)%
100/rs%
100r/s%
100s/r%
rs/100%

x/y = 100r

k/y = 100s

y = x/100r = k/100s
so,
x/k = 100r/100s = r/s
or 100r/s%

Well, this is a bit of a math puzzle, but let's see if we can figure it out! If x is r percent of y, that means x = (r/100)y. And if k is s percent of y, then k = (s/100)y.

Now, to find what percent x is of k, we can substitute the values we have:

x = (r/100)y
k = (s/100)y

So, to find the percentage, we can divide x by k and multiply by 100:

(x/k) * 100 = [(r/100)y / (s/100)y] * 100 = (r/s) * 100

Therefore, x is (r/s) * 100 percent of k.

In other words, the answer is 100r/s%. But don't worry, math can be quite the circus sometimes!

To find out what percent x is of k, we can set up the following equation:

x = r% of y (equation 1)
k = s% of y (equation 2)

Now, let's solve for y in equation 2:

y = k / (s/100) (divide both sides by s/100)

Substitute the value of y in equation 1:

x = r% of (k / (s/100))

Now, let's simplify the expression:

x = r/100 * (k / (s/100))
x = r/100 * (k * 100 / s)
x = r * k / s

Finally, x is (r * k / s) percent of k. Therefore, the answer is:

x is (r * k / s)% of k.

To solve this problem, we need to use the given information and find the relationship between x, y, and k.

Let's start by expressing "x is r percent of y" mathematically:

x = (r/100) * y --> Equation 1

Similarly, "k is s percent of y" can be written as:

k = (s/100) * y --> Equation 2

To find the percentage relationship between x and k, we need to express x in terms of k.

From Equation 1, we can isolate y:

y = (100 / r) * x --> Equation 3

Substituting Equation 3 into Equation 2:

k = (s/100) * [(100 / r) * x]

Simplifying the equation:

k = (s * x) / r

Now, let's express x as a percentage of k:

x = (r / s) * k

We can express this as a percentage by multiplying by 100:

x = (r / s) * 100 * k

Therefore, x is (r/s) multiplied by 100 percent of k.

So, the answer is 100 * (r/s) percent of k, which can be written as 100r/s%.
