K/6 = 15/18
Solve the proportion

k = 5

Step-by-step explanation:

Step 1:  Cross multiply

k/6 = 15/18

k(18) = 6(15)

18k = 90

Step 2:  Divide both sides by 18

18k / 18 = 90 / 18

k = 5

 k = 5

Another way to do it is to multiply both sides by 6

k/6 * 6 = 15/18 * 6

k = 90 / 18

k = 5

5

Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).

So we have (k)(18) or 18k = (6)(15) or 90.

Now we have the equation 18k = 90.

Dividing both sides by 18, k = 5.

It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have which is a true statement since 15/18 reduces to 5/6.
