Question

Which property is used to find proportions?

a. Multiplicative Inverse Property
b. Means-Extremes Product Property
c. Identity property of Division
d. Commutative Property of Addition

Answer 1

Answer: Means-extremes property

Step-by-step explanation: A proportion is an equation that states two ratios are equal. For example,
`(a)/(b) = (c)/(d)` is an example of a proportion.

In the given proportion, a and d are called extremes and b and c are called means. The first property that I will be talking about states that the product of the extremes equals the product of the means.

This idea is called the means-extremes property.

So if
`(a)/(b) = (c)/(d)`, we know that ad = bc by the means-extremes property.

Answer 2

B.) Means-Extreme Product Property is the property used to find proportions.

a/b = c/d ⇒ ad = bc

a and d are extremes
b and c are means

It is a property used to find proportion because the product of extremes is equal to the product of means. Cross product property.
