im sorry im asking another question lol

Question

are 4/6 and 14/21 equivalent ratios?
i did 6 x 3.5 and it came up with 21, and 4 x 3.5 and it came up with 14, so i'm guessing it is but i'm mostly having trouble with how to explain it because this is a short essay answer type thing
here's the full question:
Use cross products to demonstrate whether the two ratios are equivalent: 4/6 and 14/21.
basically i just dont know what using cross products means, im a little on the uneducated side with ratios at the moment
thank you!

Answer 1

Let's do it a simpler way.
4/6 in its simplest form is 2/3
14/21 in its simplest form is 2/3. (Divide both the numerator and denominator by 7)
