We are given the following ratios:
We are asked to determine if the ratios are equivalent. To determine that, we will divide each element of the first ratio by 2, we get:
We get the ratio 2:9, since two ratios are equivalent if both elements of one ratio is a multiple of a corresponding element of the second ratio, and we got by dividing the first ratio by 2 the following:
This means that the given ratios are not equivalent.
