Ratio problem solving is a collection of ratio and proportion word problems that link together aspects of ratio and proportion into more real life questions. This requires you to be able to take key information from a question and use your knowledge of ratios (and other areas of the curriculum) to solve the problem.

Worked example: Solving proportions (video)
The video is a bit confusing, and I'm struggling to transfer this to solving the questions for "Solving Proportions". For example in the question: 4/z = 12/5 I understand that you begin by multiplying by z. z * 4/z = 12/5*z--> 4 = 12/5*z After this, the solution set asks you to multiply both sides by 5/12, the opposite fraction of the right side.
Algebra: Ratio Word Problems
How To Solve Proportion Word Problems? When solving proportion word problems remember to have like units in the numerator and denominator of each ratio in the proportion. Examples: Biologist tagged 900 rabbits in Bryer Lake National Park. At a later date, they found 6 tagged rabbits in a sample of 2000.
5.5: Ratios and Proportions
Determine and apply a constant of proportionality. Use proportions to solve scaling problems. Ratios and proportions are used in a wide variety of situations to make comparisons. For example, using the information from Figure 5.15, we can see that the number of Facebook users compared to the number of Twitter users is 2,006 M to 328 M. Note ...

Ratio and Proportion
For example, ⅘ is a ratio and the proportion statement is 20/25 = ⅘. If we solve this proportional statement, we get: 20/25 = ⅘. 20 x 5 = 25 x 4. 100 = 100. Check: Ratio and Proportion PDF. Therefore, the ratio defines the relationship between two quantities such as a:b, where b is not equal to 0. Example: The ratio of 2 to 4 is ...
Worked out Problems on Ratio and Proportion
More solved problems on ratio and proportion are explained here with full description. 4. A bag contains $510 in the form of 50 p, 25 p and 20 p coins in the ratio 2 : 3 : 4. Find the number of coins of each type. Solution: Let the number of 50 p, 25 p and 20 p coins be 2x, 3x and 4x. Then 2x × 50/100 + 3x × 25/100 + 4x × 20/100 = 510.
6.5 Solve Proportions and their Applications
The proportion method for solving percent problems involves a percent proportion. A percent proportion is an equation where a percent is equal to an equivalent ratio. For example, 60% = 60 100 60% = 60 100 and we can simplify 60 100 = 3 5 . 60 100 = 3 5 .
