Answer:
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Answer:
Write a proportion using the ratios. Find the cross products. If the cross products are equal, then the ratios form a proportion.
