Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d.
Step-by-step explanation:
A proportion is just a statement that two ratios (i.e. fractions) are equal. So, for example, 12 and 24 form a proportion since 24=12 (you can see this by reducing 24). Since the equality we get at the end is true, the fractions do, indeed, form a proportion.
