Use cross products to demonstrate whether or not the two ratios are equivalent:
4/6 and 14/21.
Please help ASAP
To determine if two ratios are equivalent, you can use the cross product method, which involves comparing the products of the numerator of the first ratio with the denominator of the second ratio, and vice versa.
Let's do the cross products for the given ratios:
For 4/6 and 14/21, the cross products would be:
First ratio: (4 * 21) = 84
Second ratio: (6 * 14) = 84
If the cross products for both ratios are equal, then the ratios are equivalent. In this case, since 84 is equal to 84, we can conclude that the two ratios 4/6 and 14/21 are indeed equivalent.
4/6 = 14/21 ????
4 * 21 = 6 * 14 ???
84 = 84 ???? usually
another way
4/2 / 6/2 = 2/3
14/7 / 21/7 = 2/3 remarkable
