How do you set up a double number line?

Back

A double number line is set up by drawing two parallel lines, each representing a different quantity, and marking equal intervals to show the relationship between the two quantities.

If a recipe calls for 2 eggs for every 5 cups of milk, how can you find the number of eggs needed for a different amount of milk?

Back

You can use a proportion or a double number line to find the equivalent number of eggs for the given amount of milk.

Front

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

Back

If you have a ratio a:b and you know one of the values (x), you can find the missing value (y) using the formula y = (b/a) * x.

Front

How do you interpret a graph that shows a ratio?

Back

To interpret a graph showing a ratio, identify the axes, understand what each axis represents, and look for the relationship between the two quantities.

Front

What does the slope of a line in a ratio graph represent?

Back

The slope of a line in a ratio graph represents the rate of change between the two quantities being compared.

Front

How can you use a graph to find the value of a ratio at a specific point?

Back

You can locate the specific point on the graph and read the corresponding value from the axes.

Front

What is the relationship between time and distance in a rate problem?

Back

In a rate problem, the relationship between time and distance can often be expressed as a ratio, where distance = rate × time.

Front

How do you calculate the total distance traveled if you know the rate and time?

Back

Total distance can be calculated using the formula: Distance = Rate × Time.

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something (e.g., miles per hour).
