Troubleshooting Common Issues

Misunderstanding the Question

Sometimes, the question 'What is 30% of 700' can be confused with:

• 30% plus 700: Remember, we're talking about part of the number, not the whole.
• 700 is 30% of what number: Here, you'd need to solve for the whole using the formula: 700 = 0.30x where x is the unknown number, so x = 700/0.30 = 2333.33.

Rounding Errors

• Rounding: When dealing with money, always consider rounding. If you need to pay 210.67 dollars, rounding up to 211 dollars might be necessary for practical purposes.
