let's check if the following ratios are in proportion or not, by multiplying the means together and extremes together.
if the answers come equal, then they are in proportion and if not, then they aren't
20×3.5=7 and 1×7.5=7.5
as you can see the resilts are not equal, this means that the ratios are not in proportion.
