Is 4/9 and 2/4 Proportional?
Are you looking to find out whether 4/9 and 2/4 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 4/9 and 2/4. 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 4/9 equals 2/4 in a different proportion. Let's look at it visually and use letters to explain how proportions work:
So how do we know if 4/9 and 2/4 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.
Let's first work out if A (4) x D (4) is equal to B (9) x C (2):
4 x 4 = 16
9 x 2 = 18
As we can see, 16 does NOT equal 18 so we can say that 4/9 and 2/4 are NOT proportional.
By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 4/9 is 4/9 and the simplest form of 2/4 is 1/2, so 4/9 and 2/4 are NOT proportional to each other.
That's all there is to it when comparing 4/9 and 2/4 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.
