Solving ratio problems
Solve ratio problems in Grade 6 math by setting up proportions and cross-multiplying to find unknown quantities, applying this skill to real-world comparisons and scaling situations.
Key Concepts
To find an unknown actual count, first set up a ratio box. Second, find the constant factor using a complete row. Third, multiply the ratio number of the unknown item by the constant factor to find the final answer.
$$ \text{Ratio} \times \text{Constant Factor} = \text{Actual Count} $$.
The ratio of apples to oranges is 3:4. If there are 12 apples, how many oranges? The factor is $12 \div 3 = 4$. So, $4 \times 4 = 16$ oranges.
