Question

Solve for k 10/3= k/9

Answer 1

Answer:

k = 30

Step-by-step explanation:

$\frac{10}{3}=\frac{k}{9}\\\\\frac{k}{9}=\frac{10}{3}\\\\k=\frac{10}{3}*9\\\\k=10*3=30$

Answer 2

Answer:

k = 30

Step-by-step explanation:

$\frac{10}{3}$ = $\frac{k}{9}$

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
