Brian McLogan・3 minutes read
The instructor explains two methods for solving proportions, stressing the importance of using parentheses when multiplying terms. By carefully following the steps and isolating the variable, the correct solution can be found while maintaining accuracy in calculations.
Insights
- When solving proportions, it is crucial to use either the least common denominator (LCD) method or cross multiplying, while also emphasizing the necessity of using parentheses during term multiplication to ensure correct distribution and simplification.
- The key to solving proportions lies in meticulously following the steps of adding and subtracting terms on both sides of the equation, ultimately isolating the variable to obtain the final value. Accuracy in calculations and the proper utilization of parentheses are highlighted as essential for achieving the correct solution.
