Step-by-step explanation:
but it's probably better than where i am
Method 1:
In order to solve for this, we have to find out how many words Ryan can type in one minute first.
can be simplified into 
(This is just normal simplifying, all you had to do was divide both sides by 12)
Now that we have our rate,
, we can figure out how many words Ryan can type in 20 minutes
* 20/20 =
Ryan can type 1000 words in 20 minutes
Method 2:
You can use two fractions in order to solve this equation:
= 
The 'x' on the right is a variable because we don't know what the number is.
Simplify:
= 
Cross multiply:
1 * x = 50 * 20
x = 1000
Ryan can type 1000 words in 20 minutes
Good luck! If you have any questions, just ask :))
