Proportions - Game #2

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you solve a proportion?

Back

To solve a proportion, cross-multiply the terms and then isolate the variable.

Front

What is the cross-multiplication method?

Back

The cross-multiplication method involves multiplying the numerator of one ratio by the denominator of the other ratio.

Front

If a/b = c/d, what is the cross-multiplication result?

Back

The result is ad = bc.

Front

What does it mean if two ratios are in proportion?

Back

It means that the two ratios express the same relationship between their respective quantities.

Front

How can proportions be used in real-life situations?

Back

Proportions can be used to solve problems involving scaling, such as recipes, maps, and model building.

Front

What is a direct variation?

Back

Direct variation is a relationship between two variables where one variable is a constant multiple of the other.

Front

What is an inverse variation?

Back

Inverse variation is a relationship where one variable increases as the other decreases, expressed as xy = k.

Front

How do you determine if two ratios are equivalent?

Back

Two ratios are equivalent if their cross-products are equal.

Front

What is the formula for finding a missing value in a proportion?

Back

If a/b = c/x, then x = (b * c) / a.
