Question

A tank that is 40% full contains 648 gallons of water. Use a double number line to find the maximum capacity of the water tank.

 

Draw your double number line on paper, take a picture, and upload it using the image upload icon .

If you do not have the ability to upload an image of your work type "Number line is on paper."

 

Answer 1

We already know that

Double number lines are best used to visualize equivalent ratios and describe a ratio relationship between two quantities.

start with the par 40% - 648 gal and let's calculate the other missing data

to find 10%-------> multiply 648 gals by (1/4)

to find 20%-------> multiply 648 gals by (1/2)

to find 30%-------> multiply 648 gals by (3/4)

to find 50%-------> multiply 648 gals by (5/4)

to find 60%-------> multiply 648 gals by (6/4)

to find 70%-------> multiply 648 gals by (7/4)

to find 80%-------> multiply 648 gals by (8/4)

to find 90%-------> multiply 648 gals by (9/4)

to find 100%-------> multiply 648 gals by (10/4)

Here is what the numbers would look like on a number line. They are lined up.

10% 20% 30%  40%  50% 60% 70% 80% 90% 100%

162  324  486  648   810  972  1134 1296 1458 1620
