Question

Solve for k
10/3= k/9

Answer 1

k = 30

Explanation:

`(10)/(3)` =
`(k)/(9)`

We can easily solve this by cross multiplying. Multiply 10 by 9, and multiply the variable (k) by 3.

10 x 9 = 90

3 x k = 3k

These two (90 and 3k) are equal to one another and thus can both be set up into an equation.

3k = 90

Solve for k.

3k/3 = 90/3

k = 30

Answer 2

k = 30

Explanation:

`(10)/(3)=(k)/(9)\\\\(k)/(9)=(10)/(3)\\\\k=(10)/(3)*9\\\\k=10*3=30`
