Is 729/313 and 142/643 Proportional?
Are you looking to find out whether 729/313 and 142/643 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 729/313 and 142/643. 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 729/313 equals 142/643 in a different proportion. Let's look at it visually and use letters to explain how proportions work:
So how do we know if 729/313 and 142/643 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 (729) x D (643) is equal to B (313) x C (142):
729 x 643 = 468747
313 x 142 = 44446
As we can see, 468747 does NOT equal 44446 so we can say that 729/313 and 142/643 are NOT proportional.
By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 729/313 is 2 103/313 and the simplest form of 142/643 is 142/643, so 729/313 and 142/643 are NOT proportional to each other.
That's all there is to it when comparing 729/313 and 142/643 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.
