Well, you can write ratios in many different forms. These forms include:
55:33
55/33

I think it’s C but i’m so sorry if it’s wrong
2 and 9 are factors<span> of 18.</span>
<span>When we have two or more given numbers, we can find the largest factor that both numbers have in common. This is called the </span>GCF<span> or the </span>Greatest Common Factor.
There are several different methods that can be used to find the GCF. Let's take a look at some of the methods.
Method 1:<span> List out the factors.</span>
<span>Example: Find the GCF of 64 and 96. </span>
Step 1:<span> List the factors of each number. </span>
64: 1, 2, 4, 8, 16, 32, 64
96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Step 2:<span> Look for factors that both lists have in common.</span>
Step 3:<span> Pick out the largest factor that both lists have in common and call this the GCF.</span>
Therefore, the GCF of 64 and 96 is 32.
Method 2:<span> Upside Down Division</span>
Find the GCF of 280 and 144.
Step 1:<span> Place the numbers inside an upside down division bar.</span>
Step 2:Now, we need to divide both numbers by a common factor. Because both of the numbers are even, we could start with 2.The answer goes underneath the bar.
Step 3:<span> We will continue to divide until we have two numbers that are relatively prime. Remember that relatively prime means two numbers that do not have any common factors other than 1.</span>
<span>35 and 18 are relatively prime. </span>
Step 4:<span> Now we take all of the factors on the side and multiply them together.</span>
To answer this we would need the expressions given.
Supplementary angles need to add up to 180 degrees.
Subtract Y from 180:
X = 180 - 156 = 24
X = 24 degrees
