Module 1 Mid-Module Review Sheet for Test1. Nesaquake Middle School requires that there be at least 5 chaperones per class of 75
students. What is the chaperone to student ratio in its VALUE form? ____________________
2. 85 sets of Lesson #13 were copied for the math students on Team 6C. At the end of
the day, 10 extra copies were leftover. Write all answers in their VALUE form.
a. What was the ratio of the number of sets that were taken to the total amount
of sets copied? _____________
b. What is the ratio of number of sets leftover to number of sets taken?
______________
3. It takes approximately 95 gallons of water to properly irrigate 10 square feet of
farmland. Borella’s farm has 300 square feet of farmland it needs to irrigate. They
predict that they will need 2700 gallons of water to properly irrigate this piece of land.
Is their prediction correct? Prove or disprove this by checking if the ratios are
equivalent. Check one or the other and show all work (choose a method of proof).
_____Yes, the value, c (constant), is: ____________
_____No, an equivalent ratio would be: _____________
4. At NMS there are 2 students that take advanced biology in 8th grade for every 11
students that take regular 8th grade science. If there are 243 more students taking
regular 8th grade science than students taking advanced biology, find the
number of students taking advanced biology. Use a tape diagram to justify your
answer.

c) Use the table to make a list of ordered pairs to plot in a coordinate plane.
(2,4) , (3,6), (4 ,8), (5,10), (6,12 )
d) Graph the ordered pairs in the coordinate plane. Label your axes and create a title for
the graph. Connect the ordered pairs using a line. **points will be deducted for missing labels

e) Based on the problem, how many commercials on cars can we expect to see for 7 ½
hours of TV programming? _____15__________
Use the table or graph to justify your answer and explain below.
Using the graph, I found 7½ along the x-axis. I followed that up to the line and then
looked over to the y-axis to see that it was 15 commercials. All points along the line
represent equivalent ratios.
8. Mrs. Dean is mixing paint. The mixture requires 4 cups of red for every 3 cups of
blue. Mrs. Stebben’s mixture requires 3 cups of red for every 2 cups of blue.
A.) Complete both charts.
B.) Circle the two ratios you can use to compare.

Blue (cups) 2 4 6 8
C) Which mixture will have a stronger red tint? ___Mrs. Stebbins______________
D) Explain why. Be specific by using evidence/data.
Mrs. Stebbins will have a stronger red tint because she uses one more cup of red
(9) than Mrs. Dean (8) for the same about of blue (6).
