INTRO
A ratio is a comparison of two quantities. It tells us how much of one thing there is compared to another thing.

Ratios can be used in a bunch of different settings, including social media. Depending on how much you use TikTok, you may have actually seen “ratio” in the comments section.

The term is often used to start a challenge in which a user tries to get more likes on their comment than the original post or comment they’re responding to.

In the image above, we can see that TikTok’s comment has 89.3K likes whereas Slushy’s comment has 579.5K likes.

We can use this information to write the ratio of TikTok’s likes to Slushy’s likes as a fraction, with a colon, or in words:

FractionColonWords
Regardless of how we write the ratio, we can clearly see that TikTok got ratioed and took an L here. 🥴 In simplest form, for every 1 TikTok like, there were about 6 Slushy likes.

Simplest Form

The simplest form of a ratio is when there are no more numbers (other than 1) that both sides of the ratio can be evenly divided by.

Writing Ratios

A ratio is a comparison of two quantities. It tells us how much of one thing there is compared to another thing.

There are different ways to write a ratio: as a fraction, with a colon, or in words.

Equivalent Ratios

These ratios below are all equivalent. As long as we multiply or divide both sides of a ratio by the same number, we’ll have equivalent ratios.

Check out our lesson on to learn more about equivalent ratios!

Types of Ratios

There are two types of ratios:

  • A part-to-part ratio compares one part of a group to another part of the same group.
  • A part-to-whole ratio compares one part of a group to the total parts in the group.
Let’s walk through some step-by-step examples of writing ratios!

EXAMPLE 1

Let's start by finding the ratio of gold CDs to silver CDs:
💿💿📀📀📀📀📀

Step 1. Determine the items we’re comparing.

Ratio of gold CDs to silver CDs

Step 2. Determine the amount of each item.

5 gold CDs to 2 silver CDs

Step 3. Write the ratio comparison.

We can write the ratio as a fraction, with a colon, or in words.

Step 4. Simplify (if needed).

Divide the ratio amounts by common factors until the only common factor left is 1.
In this case we don't need to do any simplification, since there are no common factors.
So, the ratio of gold CDs to silver CDs is or or .

EXAMPLE 2

Amazing! Now let's find the ratio of popcorn to all snacks:
