Question

Tiffany is filling her daughters pool with water from a hose. She can fill the pool at a rate of 1/10 gallons/second. Create at least three equivalent ratios that are associated with the rate. Use a double number line to show your work.

Answer 1

Three equivalent ratios that are associated with this rate would be 6 gallons/1min, 360gallons/1 hour and 720 gallons/2hours.
I'm sorry but I can't explain or show how to use a double number line for this question.
