Is 884/457 and 421/925 Proportional?

Are you looking to find out whether 884/457 and 421/925 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 884/457 and 421/925. Let's get to it!

Okay, so first off we are referring to this is a proportion, but it can also be considered a ratio. The question we are really asking here is whether 884/457 equals 421/925 in a different proportion. Let's look at it visually and use letters to explain how proportions work:

Now these look like fractions and we could call the top number of each a numerator and the bottom number of each the denominator but, when working with proportions we need to refer to them differently.

The numbers in the A and D positions are called the "extremes" and the numbers in the B and C position are called the "means".

So how do we know if 884/457 and 421/925 are proportional to each other? The core defining property of any proportion is that the product of the means is equal to the product of the extremes.

What does that mean? Well in simple terms it means A multiplied by D must equal B multiplied by C. You could also consider these ratios to be fractions and then simplify them down to their lowest terms and compare them. If they are equal, then they are proportional.

Let's first work out if A (884) x D (925) is equal to B (457) x C (421):

884 x 925 = 817700

457 x 421 = 192397

As we can see, 817700 does NOT equal 192397 so we can say that 884/457 and 421/925 are NOT proportional.

Let's also try this by reducing the two fractions/ratios down to their lowest terms and see if the resulting ratio is equal.

By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 884/457 is 1 427/457 and the simplest form of 421/925 is 421/925, so 884/457 and 421/925 are NOT proportional to each other.

That's all there is to it when comparing 884/457 and 421/925 to see if the ratios are proportional. The easiest method is to make sure the product of the "means" is equal to the product of the "extremes" by multiplying A and D and B and C to make the resulting number matches.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!
