Is 869/12 and 639/902 Proportional?
Are you looking to find out whether 869/12 and 639/902 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 869/12 and 639/902. 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 869/12 equals 639/902 in a different proportion. Let's look at it visually and use letters to explain how proportions work:
So how do we know if 869/12 and 639/902 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 (869) x D (902) is equal to B (12) x C (639):
869 x 902 = 783838
12 x 639 = 7668
As we can see, 783838 does NOT equal 7668 so we can say that 869/12 and 639/902 are NOT proportional.
By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 869/12 is 72 5/12 and the simplest form of 639/902 is 639/902, so 869/12 and 639/902 are NOT proportional to each other.
That's all there is to it when comparing 869/12 and 639/902 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.
