How do you subtract fractions with different denominators?

You find a common denominator, for example, if you want to subtract 3/4 minus 1/2 you would have to multiply 1/2 by 2/2, which equals 2/4, then you can do 3/4-2/4, which is 1/4. Sorry if it’s a bit confusing, hope it helps!

Answer:

When solving fractions with different denominators, you first need to make the denominators the same.

Example:

$\frac{1}{2}$ - $\frac{1}{4}$

You need to make sure the denominators are the same.

Can 2 get multiply by something and will be 4?

The answer is yes, if you multiply 2 by 2, it will change the 2 to 4. You have to multiply the equation $\frac{1}{2}$ by $\frac{4}{4}$ (which is also equivalent to 1) and which change the equation to $\frac{2}{4}$ .

And now you can subtract because the denominators are the same.

Hope this helps!

Step-by-step explanation:

I would use Pythagorean Theorem to setup two equations since there are two triangles with no angle information.

Let $BC=x+(99-x)$ where $x$ is equal to the first partition of $BC$ (reading from left to right) and $(99-x)$ is equal to the second partition of $BC$ (reading from left to right).
