Ask Me Help Desk - Ratios please help! This (/) the slash means fraction okay

What you have to do basically is to multiply/divide both sides to get the variable alone on one side.

Take (k) for example:

$\frac{781}{55} = \frac{639}{h}$

Multiply both sides by h, what do you get?

$\frac{781}{55} \times h= \frac{639}{h} \times h$

$\frac{781h}{55}= \frac{639}{\cancel{h}} \times \cancel{h}$

$\frac{781h}{55}= 639$

Now, multiply by 55, then divide by 781;

$\frac{781h}{55} \times \frac{55}{781}= 639\times \frac{55}{781}$

$\frac{\cancel{781}h}{\cancel{55}} \times \frac{\cancel{55}}{\cancel{781}}= 639\times \frac{55}{781}$

$h = 639\times \frac{55}{781}$

Now you can simplify that.

Can you try to solve the others and post what you get for them? :)
