# How do you solve k/9=10/18?

Jul 28, 2018

k=5

#### Explanation:

$\frac{k}{9} = \frac{10}{18}$
start by cross-multiplying, so as to keep the variable and the constants on opposite sides.
therefore, k= $\frac{90}{18}$
which implies that, k=5

$k = 5$

#### Explanation:

Here ,

$\frac{k}{9} = \frac{10}{18}$

Multiplying both sides by $9$

$\frac{k}{\cancel{9}} \times \cancel{9} = \frac{10}{\cancel{18}} ^ 2 \times \cancel{9}$

$k = \frac{10}{2}$

$k = \frac{\cancel{2} \times 5}{\cancel{2}}$

$k = 5$

$k = 5$

#### Explanation:

We can cross multiply to get the equation

$18 k = 90$

Lastly, we can divide both sides by $18$ to get

$k = 5$

Hope this helps!
