Comparing Ratios and Unit Rates

The video emphasizes the importance of showing strategy in tests, as it accounts for half the credit. It covers calculating unit rates to compare speeds, using alternative methods like TRF and equivalency ratio tables, and understanding division to avoid common mistakes. The video also includes a practical example of comparing parachute descent rates using ratios.

Why is it important to show a strategy when solving problems?

• It is only for extra credit.

• It is only required for difficult problems.

• It is not necessary if the answer is correct.

• It helps in getting full credit even if the answer is wrong.

How do you set up a template for calculating unit rates?

• Seconds over meters

• Seconds over feet

• Feet over seconds

• Feet over minutes

What is the unit rate for a runner covering 60 feet in 10 seconds?

• 10 feet per second

• 6 feet per second

• 60 feet per second

• 1 foot per second

Which method can be used as an alternative to unit rates for comparing speeds?

• Using a stopwatch

• Equivalency ratio tables

• Guessing

• Using a calculator

What happens if you multiply both the numerator and denominator by the same number in a ratio?

• The ratio becomes zero

• The ratio remains the same

• The ratio changes

• The ratio becomes negative

When dividing 60 by 10, where should the smaller number be placed?

• It doesn't matter

• On top of the division house

• Outside the division house

• Inside the division house

What is the correct way to ensure a whole number result when dividing?

• Place the larger number outside the house

• Divide by zero

• Use a calculator

• Place the smaller number outside the house

How can you determine which parachute descends slower?

• By comparing the material of the parachutes

• By comparing the feet descended per second

• By comparing the weight of the parachutes

• By comparing the number of colors

What is the value of the ratio 10 to 4 when reduced to simplest terms?

• 10 to 2

• 4 to 1

• 5 to 2

• 2.5 to 1

Which method can be used to compare two ratios effectively?

• Using a ruler

• Using equivalency ratio tables

• Using a protractor

• Using a compass
