1. Let's clarify the problem: You are asking if you should multiply each side of an equation by 100. 2. The general rule is: To eliminate decimals or percentages, you can multiply both sides of an equation by 100 to simplify calculations. 3. For example, if you have an equation like $0.25x = 5$, multiplying both sides by 100 gives: $$100 \times 0.25x = 100 \times 5$$ which simplifies to: $$25x = 500$$ 4. This step is valid because multiplying both sides of an equation by the same nonzero number does not change the equality. 5. However, you should only multiply by 100 if it helps simplify the equation or remove decimals/percentages. 6. Always ensure to perform the same operation on both sides to maintain balance. In summary, yes, you multiply each side by 100 if it helps simplify the equation, especially to clear decimals or percentages.
