Using Ratio Tables

Front

What is a ratio?

Back

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as 'a to b' or a:b.

Front

How do you create a ratio table?

Back

A ratio table is created by listing pairs of equivalent ratios in a table format, allowing for easy comparison and calculation.

Front

What does it mean to find a missing number in a ratio table?

Back

Finding a missing number in a ratio table involves using known ratios to calculate an unknown value that maintains the proportional relationship.

Front

If a ratio is 3:4, what is the equivalent ratio for 6:8?

Back

6:8 is equivalent to 3:4 because both ratios simplify to the same fraction (3/4).

Front

What is the purpose of using ratio tables?

Back

Ratio tables help visualize and solve problems involving proportional relationships, making it easier to find missing values.

Front

How can you use a ratio table to solve for a variable?

Back

You can set up a ratio table with known values and use cross-multiplication to solve for the unknown variable.

Front

What is the relationship between ratios and fractions?

Back

Ratios can be expressed as fractions, where the first quantity is the numerator and the second quantity is the denominator.

Front

If Hilbert burns 120 calories in 30 minutes, how many calories does he burn in 1 minute?

Back

He burns 4 calories per minute (120 calories ÷ 30 minutes = 4 calories/minute).

Front

What is the missing value if the ratio is 2:5 and the known value is 10?

Back

The missing value is 4 (because 2/5 = x/10, solving gives x = 4).

Front

How do you determine if two ratios are equivalent?

Back

Two ratios are equivalent if they simplify to the same fraction or if their cross-products are equal.
