Is 839/644 and 658/40 Proportional?
Are you looking to find out whether 839/644 and 658/40 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 839/644 and 658/40. 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 839/644 equals 658/40 in a different proportion. Let's look at it visually and use letters to explain how proportions work:
So how do we know if 839/644 and 658/40 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 (839) x D (40) is equal to B (644) x C (658):
839 x 40 = 33560
644 x 658 = 423752
As we can see, 33560 does NOT equal 423752 so we can say that 839/644 and 658/40 are NOT proportional.
By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 839/644 is 1 195/644 and the simplest form of 658/40 is 16 9/20, so 839/644 and 658/40 are NOT proportional to each other.
That's all there is to it when comparing 839/644 and 658/40 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.
