Use cross products to demonstrate whether or not the two ratios are equivalent:
4/6 and 14/21.

Answer 1

cross products: a/b = c/d is also equal to ad = bc

so, essentially you’re just drawing two diagonal lines from one side to the other, multiplying those numbers together, and setting them equal

so: 4/6 and 14/21 = (4*21 = 6*14) = (84 = 84)

84 is equal to 84 so these two ratios are equivalent.
