How to use Ratios and Proportions to Solve Real World Problems


By mrtedmartin

Instructor uses a Power Point presentation to demonstrate how to use ratios and proportions to solve problems real world problems. Unit rates are discussed and definitions are given. Solving unit rate problems are modeled and a calculator is used for computation.

Basic rate problems

Speed translation | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy


By Khan Academy

This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!
