  1. 2.6 – Ratios & Proportions

  2. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 3.5 14

  3. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply.

  4. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.5 14

  5. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.5 14

  6. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.5 14 28

  7. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.5 14 28 =

  8. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.514 28 = 28

  9. Ex. 1 Determine whether each pair of ratios are equivalent ratios. a) 2 , 8 *Set them equal to each 3.5 14 other & cross multiply. 2 = 8 3.514 28 = 28 This is true, so they are equivalent ratios.

  10. Ex. 1 Determine whether each pair of ratios are equivalent ratios. b) 15 , 35*Set them equal to each 36 42 other & cross multiply.

  11. Ex. 1 Determine whether each pair of ratios are equivalent ratios. b) 15 , 35*Set them equal to each 36 42 other & cross multiply. 15= 35 3642 1260 = 630 This is false, so they are not equivalent ratios.

  12. Ex. 2 Solve each proportion. If necessary, round to the nearest hundredth. a) x =3 10 5
