Use Percent Formula: Use the percent formula: Percent (as a decimal) × Whole = Part. Identify the Percent, Whole, and Part in the given problem. The percent formula becomes: Percentage of pennies × Total number of coins = Number of pennies.
Identify Values: Choose the correct option to find the equation after plugging in the values. Use x for the unknown value. After plugging in the values the equation becomes: x×600=240.
Solve for Unknown: We found: x×600=240. Solve for x by isolating it on one side of the equation. Dividing both sides of the equation by 600, we get: ((x×600)/600)=(240/600)x=240/600x=0.4.
Convert to Percent: Convert 0.4 into a percent. 0.4 (0.4×100)% 40%.
