Ratio Problems Involving Totals
Ratio Problems Involving Totals is a skill on Pengi from Lesson 45: Ratio Problems Involving Totals in Saxon Math, Course 3.
Key Concepts
Property When a problem involves a total, add the ratio numbers to create a ratio for the total. Use a three row table to organize the parts and the total amount.
Examples Ratio of wins to losses is 5:2. In 21 games, find wins (w): $\frac{5}{7} = \frac{w}{21} \rightarrow w=15$. Ratio of ducks to geese is 4:3. With 16 ducks, find the total birds (b): $\frac{4}{7} = \frac{16}{b} \rightarrow b=28$.
Explanation Think of it as a power up! Adding ratio parts creates a new part to total ratio, which is the secret key you need to solve for any missing number in the problem.
