$21.80 because you will do 20% over 100% = x over $26. Than you will do 26 times 20 divided by 100, and you get 5.2, than you will do 26-5.2 and you get $21.80
Answer: OPTION D.
Step-by-step explanation:
For this exercise it is important to remember the following Trigonometric Functions:
Knowing this, we can identify that:
Therefore, the ratio 
is equivalent to this Trignometric function:
Answer:
6/45 and 20/45
Step-by-step explanation:
The least common denominator is the least common multiple (LCM) of 9 and 15.
The factors of those numbers are ...
9 = 3·3
15 = 3·5
The LCM is the product of the unique factors to their highest powers:
3·3·5 = 45
__
To make 2/15 have a denominator of 45, we need to multiply by 3/3:
2/15·3/3 = 6/45
To make 4/9 have a denominator of 45, we need to multiply by 5/5:
4/9·5/5 = 20/45
The desired fraction pair is 6/45 and 20/45.
So basically it sounds like it wants you to make the denominators match.
Here's an example:
3/4 and 1/2
First you would find the Least Common Multiple (LCM), which of these two numbers is 4.
3/4 and 2/4 Then you would multiply the denominator the same amount you multiplied the denominator.
and voila! 3/4 and 2/4 have matching denominators
