<h2>
![w = \frac{70y}{9x}](https://tex.z-dn.net/?f=w%20%3D%20%20%5Cfrac%7B70y%7D%7B9x%7D%20)
</h2>
Step-by-step explanation:
<h3>
![\frac{9x}{10y} = \frac{7}{w}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9x%7D%7B10y%7D%20%20%3D%20%20%5Cfrac%7B7%7D%7Bw%7D%20)
</h3>
First of all cross multiply
We have
<h3>
![9xw = 70y](https://tex.z-dn.net/?f=9xw%20%3D%2070y)
</h3>
Next divide both sides by 9x to make sure that w stands alone
That's.
<h3>
![\frac{9xw}{9x} = \frac{70y}{9x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9xw%7D%7B9x%7D%20%20%3D%20%20%5Cfrac%7B70y%7D%7B9x%7D%20)
</h3>
We have the final answer as
<h3>
![w = \frac{70y}{9x}](https://tex.z-dn.net/?f=w%20%3D%20%20%5Cfrac%7B70y%7D%7B9x%7D%20)
</h3>
Hope this helps you.
