A proportion is an equation that shows two ratios are equivalent.

A proportion is a comparison of two quantities.

A proportion is only applicable to whole numbers.

A proportion is used only in statistics.

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

Two ratios are proportional if they have different units.

Two ratios form a proportion if their sums are equal.

Two ratios are proportional if they are greater than one.

9/12 = 15/20.

3/4 = 6/8.

5/7 = 10/15.

7/9 = 21/27.

Proportions can be used in cooking and recipes to maintain ingredient ratios.

Proportions are only used in algebra.

Proportions are used exclusively in finance.

Proportions are irrelevant in construction.

Divide each side by the sum of the ratios.

Subtract coordinates and simplify.

To solve, cross-multiply the terms and solve the resulting equation for the unknown variable.

Factorize all terms and solve.

Yes, proportions can involve decimals as well as fractions.

No, proportions can only involve fractions.

Decimals are irrelevant in proportions.

Proportions can only involve integers.

Using decimals instead of fractions.

Focusing on denominators only.

Adding units after solving the proportion.

A common mistake is not ensuring that the ratios are set up with the same units in both numerators and denominators.

It uses random adjustments for representation.

A scale model uses proportions to represent an object smaller or larger than the actual object while keeping accurate relative dimensions.

A scale model uses proportion to match exactly the object's color.

It scales only the volume of the model.

Equivalent fractions are used to simplify or rewrite proportions to show their equality more clearly.

Equivalent fractions confuse proportion problems.

Equivalent fractions do not play a role in proportions.

They are used to measure temperature changes.

Add numerators and solve for x to get x = 7.

Square the fractions and solve.

Cross-multiply to get 9x = 18, then solve for x, giving x = 2.

Subtract 6 from each side.

They are not used in geometry.

Proportions are used in geometry to prove the similarity of triangles and solve for unknown side lengths.

Proportions calculate the angles of polygons.

They only apply to circle equations.

A proportion is a statement that two ratios are equal, while a ratio is a comparison of two quantities.

Ratios involve more complex equations than proportions.

Proportions only deal with financial terms.

Ratios can only be used with time-related measurements.

Direct proportion is when one value remains constant regardless of other changes.

Two quantities are in direct proportion if they increase or decrease at the same rate.

It means one quantity is always double the other.

Direct proportion is applicable to discrete variables only.

7/x = 10/5.

7/x = 5/10.

7/x = 12/14.

7/10 = x/5.

It is used to rewrite ratios as decimals.

Cross-multiplication calculates averages between two fractions.

Cross-multiplication is a method used to solve proportions by multiplying the outer terms by each other and the inner terms by each other, then equating the two products.

It involves adding all terms and dividing by the number of terms.
