Is 42/390 and 914/290 Proportional?
Are you looking to find out whether 42/390 and 914/290 form a proportion? In this article we'll compare these two to determine if there is a proportional ratio between 42/390 and 914/290. 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 42/390 equals 914/290 in a different proportion. Let's look at it visually and use letters to explain how proportions work:
So how do we know if 42/390 and 914/290 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 (42) x D (290) is equal to B (390) x C (914):
42 x 290 = 12180
390 x 914 = 356460
As we can see, 12180 does NOT equal 356460 so we can say that 42/390 and 914/290 are NOT proportional.
By reducing the two ratios down to their simplest/lowest form we can see that the simplest form of 42/390 is 7/65 and the simplest form of 914/290 is 3 22/145, so 42/390 and 914/290 are NOT proportional to each other.
That's all there is to it when comparing 42/390 and 914/290 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.
