2. Order -1, -1.8, 2/5, -1 1/4, and -3/8 from least to greatest.
3. You set up an in-line skating course 25 feet long to practice weaving around cones. You want a cone every 2 1/2 feet, but not at the start or end of the course.
How many cones will you need?
4. A large floral carpet of begonias is being designed to mimic the carpet made every few years at the Grand Place in Brussels, Belgium.

Find the drawing's scale.
5. Suppose a basketball league has 14 teams in Conference A and 13 teams in Conference B. One team from each conference advances to the finals. How many different team matchups could there be in the finals?
6. Given triangle ABC is similar to triangle DEC. Use the give measurement to find BC in inches.
AB = 9 in, EC = 18 in, DE = 6 in, and BC = x + 8
7. Given ABCD is similar to JKLM. Use the measurements given to find the ratio of the lengths of the corresponding sides of ABCD to JKLM in lowest terms.
BC = 6 ft, AD = 12 ft, AB = 24 ft, CD = 24 ft, LM = 52 ft, JM = 26 ft, JK = 52 ft, and KL = 13 ft.
8. Stalactites are icicle-shaped formations found on cave ceilings.
They form from minerals deposited by dripping water.
Suppose a stalactite is 8 inches long and is growing at a rate of about 1/6 inch per year.
It will take____ years for the stalactite to reach a length of 1 foot.
(Hint: Make sure you convert feet to inches before for setting up the equation to solve!)
9. A model of an aircraft has a scale of 1:51. The aircraft has a wingspan of 96.9 feet. Find the model's wingspan, in feet. Be sure to label your answer.
10. Write the decimal 0.48 as a fraction in simplest form.
11. Solve the equation - 1/10 x = 8.
12. You are driving 2,754 miles across the country.
During the first 3 days of your trip, you drive 1,377 miles.
If you continue to drive at the same rate each day, it will take___ more days to complete the trip.
Remember to include the label feet in the answer.
Ex. 16 days
13. An archer shoots 57 arrows at a target, with 45 arrows hitting the scoring area and 12 missing the scoring area. Write the ratio of the number of hits to the number of shots in three ways.
14. Give ABCD is similar to EFGH. Use the measurements to find EH in inches.
GF = 20 in, BC = 8 in, and AD = 14 in
15. You roll roll a six-sided number cube.
The probability you roll a number greater than 4 is___.
16. A map uses a scale of 1 cm : 180 m. This means that 1 centimenter in the scale drawing represents an actual distance of 180 meters. The distance between the two places on the map is 6 centimeters. What is the actual distance, in meters, between the two places. Be sure to label your answer.
17. A map has a scale of 3 centimeter : 4 kilomenters. Use the given map distance of 110 km to find the actual distance in centimeters and be sure to label your answer.
18. Given PQRS is similar to JKLM. Use the measurements given to find the length of JM.
KL + 15 ft, JK = 25 ft, QR = 12 ft, RS = 10 ft, and PS = 16 ft
19. A sing in a clothing store says take 2/3 off the marked price of a shirt. You have in cash and a gift certificate. What is the original price of a shirt you can afford to buy?
20. Find the missing value that makes the rates 195 mi/13 sec = ? mi/1 min equivalent.
21. A miniature golf course offers a free game to golfer makes a hole-in-one on the last hole. Please write your answer as a percent and round it to the hundredths place if necessary.
22. You are enlarging a photograph to make a poster.

I’ll help with some of the questions:
2. Either change all the decimals to fractions or all the fractions to decimals (probably the easier way) and put them in order.
3. Divide 25 by 2.5 for your answer but REMEMBER you don’t want a cone at the end of the course.
4. A scale is the fraction arrived at by dividing the smaller measure of width over the larger and simplifying.
5. Any of the teams in Conference A can possibly matchup with any team in conference B so the amount of different matchups are represented by 13(14!)
