Assignment 11b: Comparing Ratios
Submission Instructions: Write your answers to the
problems on paper and then scan or take photos of those
pages. If there are multiple pages to your completed
assignment, you must submit them as one multi-page
document (pdf, docx, jpg, or png).
Directions: Complete each of the following. Partial credit
will be given if enough work is shown to indicate some
understanding of the solutions.
1. The ratio table shown below indicates that a
particular shade of purple paint is made by mixing 5
pints of red paint with 6 pints of blue paint. Copy the
table onto your paper and fill in the missing cells so
that that amount of red and blue paint in each
column would create a mixture that is the same
shade of purple paint as the first mixture.
Number of pints of red paint 5

Number of pints of blue paint

2. The ratio table shown below indicates that cans of
soda are sold at a rate of 8 cans of soda for $5.20.
Copy the table onto your paper and fill in the missing
cells so that the quantities in each column are such
that the cost per can of soda remains the same as the
original price. Make sure you write the dollar
amounts correctly. That is, $5.20 is correct but $5.2 is
not a correct way to write money.

3. Student A ran 3 miles in 30 minutes and Student B
ran 5 miles in 40 minutes. Set up a pair of ratio tables
and create enough columns to satisfy both of the
following requirements:
a. For any column in each table, the number of
miles for both students is the same.
b. For any column in each table, the number of
minutes for both students is the same.
4. Refer back to problem #3 and determine which
student had a faster average speed by comparing the
columns you made in which the number of miles was
the same for both students. Clearly state which
student had the faster average speed and how you
used the quantities in those specific columns to
determine who had the faster average speed.
5. Refer back to problem #3 and determine which
student had a faster average speed by comparing the
columns you made in which the number of minutes
was the same for both students. Clearly state which
student had the faster average speed and how you
used the quantities in those specific columns to
determine who had the faster average speed.
