How do you determine if two ratios form a proportion?

Back

Two ratios form a proportion if the cross products are equal.

Front

What is the cross product of the ratios \( \frac{a}{b} \) and \( \frac{c}{d} \)?

Back

The cross product is \( a \cdot d \) and \( b \cdot c \). If \( a \cdot d = b \cdot c \), then the ratios form a proportion.

What is the formula to solve for \( x \) in the proportion \( \frac{a}{b} = \frac{x}{c} \)?

Back

The formula is \( x = \frac{a \cdot c}{b} \).

Front

What does it mean if a relationship is proportional?

Back

A relationship is proportional if the ratio between two quantities remains constant.

Front

How can you express a proportional relationship using a table?

Back

A proportional relationship can be expressed in a table by showing pairs of values that maintain a constant ratio.
