There are 3 ways to show that ratios are proportional. Can you explain at least one way? Explain how.
One way to show that ratios are proportional is through cross multiplication. When you have two ratios a:b and c:d, you can set up a proportionality equation by multiplying a and d to get one product and b and c to get the other product. You then set the two products equal to each other to prove the ratios are proportional.
For example, if you have the ratios 2:3 and 4:6, you would set up the equation as 2 x 6 = 3 x 4, which simplifies to 12 = 12, showing that the ratios are proportional.
