3. 12/3/15 Lesson 4 – 7 Ratios, Proportions, & Converting Day 1 Advanced Math/Trig

4. Learning Objective To simplify ratios To convert units of measures To solve problems using proportions

5. Measurement Conversions 1 foot = 12 inches 1 yard = 3 feet 1 mile = 5280 feet 1 meter = 100 cm 1 km = 1000 m 1 pound = 16 ounces 1 ton = 2000 lbs 1 gallon = 4 quarts 1 quart = 2 pints 1 pint = 16 ounces 1 min = 60 secs 1 hour = 60 min

6. Ratios

7. Ratios = 4 dollars/ticket = 75 miles/min

8. Ratios = 88 ft/sec

9. Ratios = 1760 yd/min

10. Proportions

11. Ratios 8x = 400(6) 8x = 2400 = 300 km

12. Ratios 2x = 48(3) 2x = 144 = 72 pints of milk = 48 pints of water

13. Ratios 5x = 3(48 – x) 5x = 144 – 3x 8x = 144 Person 1 = x Person 2 = 48 – x $18 person 1 $30 person 2

14. Ratios 100x = 30(16) 100x = 480 4.8 oz of water

15. Ticket Out the Door If a mixture contains 40% alcohol, how many ounces of alcohol are in 6 ounces of the mixture?
