Read problem and write ratio. 1 1 white tiles: total tiles 8:18 Or 4:9 in simplest form Remember to simplify! Question

Read carefully and use proportional reasoning to solve. 2 Question 2 Identify the two items you are comparing: Cost $ $12 = x No. Tiles 8 1 Divide 12 by 8 or cross multiply and divide. x= $1.50

Read the question and find the missing value. 3 3 Question 3 C.The pattern increases by $5, if 10 lbs.= $25 then 12 lbs. = $30 You can also see that each pound costs $2.50 using unit rate. So, 12 × 2.50 = $30.00

Read carefully and respond in writing. 4 Question 4 Identify items being compared. 7:2 Total Loaves : Loaves of Rye This means for every 7 loaves of bread 2 loaves will be rye.

Read the problem then solve using a proportion. Next, select the correct solution. 5 Question 5 Answer: A Identify items to compare which are dollars per hour. Total Dollars = $ 180 = x Total Hours 20 hrs 1hr Cross multiply and divide OR divide 180 by 20.

Use proportional reasoning to solve. 6 Question 6

Read the question and write the ratio. 7 Question 7

Complete the problem. 8 Question 8 Answer: B. Find the unit rate of bananas and oranges. Bananas: $1.50 ÷ 6 = $0.25 per banana. Oranges: $3.00 ÷ 5 = $0.60 per orange. So, (2 × 0.25) + (2 × 0.60) = total cost. $1.70

Use unit rate to find the answer. 8 Question 9

Write the correct ratio. 9 Question 10 Many times the comparison is in the opposite order as the facts given!!

Find the correct unit rate. 10 Question 11

Find unit rate. 11 Question 12

Read carefully then complete the problem. Question 13 First, identify items being compared. Stars: Red Stripes 50:7 Ratios can be written three ways.
