A recipe says that 2 cups of dry rice will serve 6 people. Complete the table as you answer the questions below. Be prepared to explain your reasoning.
How many people will 1 cup of rice serve?
How many people will 3 cups of rice serve? 12 cups? 43 cups?
How many people will [math]x[/math] cups of rice serve?

How was completing this table different from the previous table? How was it the same?
A plane flew at a constant speed between Denver and Chicago. It took the plane 1.5 hours to fly 915 miles. Complete the table.
How far does the plane fly in one hour?[br]
How far would the plane fly in [math]t[/math]hours at this speed?[br]
If [math]d[/math] represents the distance that the plane flies at this speed for [math]t[/math] hours, write an equation that relates [math]t[/math] and [math]d[/math].
How far would the plane fly in 3 hours at this speed? in 3.5 hours? Explain or show your reasoning.
A rocky planet orbits Proxima Centauri, a star that is about 1.3 parsecs from Earth. This planet is the closest planet outside of our solar system.
How long does it take light from Proxima Centauri to reach Earth? (A parsec is about 3.26 light years. A light year is the distance light travels in one year.)
There are two twins. One twin leaves on a spaceship to explore the planet near Proxima Centauri traveling at 90% of the speed of light, while the other twin stays home on Earth. How much does the twin on Earth age while the other twin travels to Proxima Centauri? (Do you think the answer would be the same for the other twin? Consider researching “The Twin Paradox” to learn more.)
A bakery uses 8 tablespoons of honey for every 10 cups of flour to make bread dough. Some days they bake bigger batches and some days they bake smaller batches, but they always use the same ratio of honey to flour. Complete the table.
If [math]f[/math] is the cups of flour needed for [math]h[/math] tablespoons of honey, write an equation that relates [math]f[/math] and [math]h[/math].
How much flour is needed for 15 tablespoons of honey? 17 tablespoons? Explain or show your reasoning.
IM 7.2.4 Practice: Proportional Relationships and Equations
A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75 tiles. Fill in the table with the missing values.
On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, [math]d[/math], to the number of hours flying, [math]t[/math], is [math]t=\frac{1}{500}d[/math]. How long will it take the airplane to travel 800 miles?
Each table represents a proportional relationship. For each, find the constant of proportionality, and write an equation that represents the relationship.[br][br][img]data:image/png;base64,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

A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.
Here is a polygon on a grid.
Draw a scaled copy of the polygon using a scale factor 3. Label the copy A.[br]Draw a scaled copy of the polygon using a scale factor [math]\frac{1}{2}[/math]. Label the copy B.[br][br]Is Polygon A a scaled copy of Polygon B? If so, what is the scale factor that takes B to A?
