  1. Quarter 3 Test 3 XLIII. Ratios and Rates XLIV. Proportions XLV. Customary Units of Measure XLVI. Similar Figures

  2. Oscar gets 2 hits out of his every 5 times he comes up to bat. How many hits would you expect him to have in 60 at bats? 2x = 560 2(60)=5(x) 120=5x 5 5 x = 24 hits

  3. Jason averages 4 earned runs for every 9 innings he pitches. How many earned runs would he have if he pitched 45 innings? 4=x 9 45 4(45)=9(x) 180=9x 9 9 x = 20 earned runs

  4. In 1 hour Arthur hikes 3 miles. At the same rate, how long will it take him to hike 12 miles? 1 =x 3 12 1(12)=3(x) 12=3x 3 3 x = 4 hours

  5. The rectangles are similar. What is the length of n? 6cm 4cm 6cm n 6(6)=4(n) 36=4n 4 4 n = 9 4=6 6 n

  6. RST is similar to XYZ. What is the length of XY? S Y x 14m 10m 4m Z X 4m T R 10m 10(x)=14(4) 10x= 56 10 10 x = 5.6m 10=4 14 x

  7. Find the length of h. h 6cm 18cm 72cm h=6 72 18 18(h)=6(72) 18h=432 18 18 h = 24cm

  8. Compare. Write <,> or =. < < = > > < = • 52ft_______18yd • 5gal 2qt_______ 24qt • 72in_______6ft • 256oz______15lb 4oz • 36lb________524oz • 12T 850lb______25,000lb • 100qt______25gal

  9. Which is the Better Buy?Give the rate and the unit rate. 3 apples for $.75 or 9 apples for $2.10 $.75 =$.25 3 1 $2.10 = $.23 9 1 The 9 apples for $2.10 is a better buy.

  10. Customary Units of Measure • 3ft=_____ in. • 24yd=_____ft • 10,560ft=______mi • 4lb 15oz=______oz • 7pt=________c • 4.5T=_______lb • 4 3/4lb=_______oz 36in 72ft 2mi 79oz 14c 9000lb 76

  11. If 2 ½ inches on a map represents 750 miles, how many miles are represented by 4 inches? 2.5 = 4 750 x x = 1200 miles

  12. A mother giraffe is 18.7 feet tall. Her baby is 5.25 feet tall. The baby giraffe casts a shadow that is 35.7 feet long. How long is the mother giraffe’s shadow? height 18.7 = 5.25 shadow x 35.7 18.7(35.7) = 5.25 x 667.59 = 5.25 x 5.25 5.25 x = 127.16 ft
