### Geo 7-1 Ratios and Proportions

• 1.
• 2. Students will be able to write and solve ratios Students will be able to write and solve proportions
• 3. Comparison of two quantities by division Written as: • a/b • a : b • a to b Always write in simplest form (reduced form) Make sure units of measure are the same
• 4. A bonsai tree is 18 in wide and stands 2 ft tall. What is the ratio of the width compared to the height? First convert measurements to either inches or feet Then write the ratio in simplest form 18 : 24  3 : 4
• 5. A pigmy rattlesnake has an average length of 18 inches, while a Western diamondback rattlesnake averages 5ft. 6in. What is the ratio of the length of a pigmy to a Western diamondback rattlesnake? 18 : 66  3 : 11
• 6.  The measures of two supplementary angles are in the ratio 1:4. What are the measures of the angles?  Write the ratio in words: angle 1: angle 2  Then write using variables: x : 4x  Set up an equation: x + 4x = 180  Solve the equation: x = 36  Substitute x back into the ratio Angle 1 = 1(36) = 36  Angle 2 = 4(36) = 144
• 7.  The measures of two complementary angles are in the ratio 1:3. What are the measures of the angles?  Write the ratio in words: angle 1 : angle 2  Then write using variables: x : 3x  Set up an equation: x + 3x = 90  Solve the equation: x = 22.5  Substitute x back into the ratio Angle 1 = 1(22.5) = 22.5  Angle 2 = 3(22.5) = 67.5
• 8. Compares 3 or more numbers Written as • a : b : c
• 9. The lengths of the sides of a triangle are in the extended ratio 4 : 7 : 9. The perimeter is 60 cm. What are the lengths of the sides? Write an equation: 4x + 7x + 9x = 60 Solve for x: x = 3 So the lengths of the sides are: • 4(3) = 12 • 7(3) = 21 • 9(3) = 27
• 10. When two ratios are equal Use cross products to solve proportions a = c  ad = bc b d
• 11.
• 12. x/6 = y/7 What ratio completes the equivalent proportion? • x/y = ? • 6/x = ? • (y + 7)/7 = ?
• 13. 9 = a 2 14  15 = 3 m+1 m  X = X+2 X – 1 X
• 14. Pg. 368 #2 – 20 even, 21, 26 – 28 all, 37 - 40 all 18 problems 
