Do you want to find out how to convert the part-to-part or part-to-whole ratios to fractions?

We’ll tell you everything you need to know in today’s article. Let’s dive into the details.

How Can the Ratio-to-Fraction Calculator Help You?

This handy calculator can convert any ratio to a fraction in no time. On top of that, the tool will reduce the fractions to the simplest form for you.

So, all you need to do is enter the ratio, turning it into the simplest fraction. This can be helpful in any day-to-day situation, especially when calculating odds or percentages.

You may use our ratio to percentage calculator if you wish to turn a ratio directly into a percentage value.

How To Convert Part-to-Part Ratio to Fractions?

Part-to-part ratios can come in handy when calculating the odds of an event happening.

Before we tell you how to convert them into fractions, you need to understand what part-to-part ratios are.

If there were 3 bananas and 5 apples in a bowl, the part-to-part ratio of the bananas to apples would be 3:5. So, we basically compare the value of X to the value of Y.

Say there was a classroom that contained 20 students. 8 of these students were females. So, the number of male students is 20 – 8 = 12.

Therefore, the part-to-part ratio of females to males will be 8:12. As a fraction, this ratio will be 8/12.

You’ll need to place each of the ratio terms as a numerator in a fraction. You’ll end up with 8/20 and 12/20.

After that, you can divide both numbers by the greatest common factor, which is 4.

As a result, the fraction of females in the class will be 2/5, and the fraction of males in the class will be 3/5.

How To Convert Part-to-Whole Ratio to Fractions?

Part-to-whole ratios are a little different from part-to-part ones. In this case, you’ll be comparing a certain value to the whole value. So, ratios can be converted into fractions directly.

We’re basically comparing the value of X to the value of X+Y.

Let’s use the same classroom example with 8 females and 12 males.

The part-to-whole ratio of females is 8:20, and for males, it’s 12:20. By directly turning these values to fractions, the females will be 8/20, and the males will be 12/20.

After simplifying the fractions, the results will be:

2/5 of the classroom are females

3/5 of the classroom are males
