When you're trying to figure out percentages with fractions, there are some tricks that can make it a lot easier. Here are a few helpful tips I've learned over time:

1. Change Fractions to Decimals: This can be the easiest way to do your calculations. To turn a fraction into a decimal, just divide the top number (numerator) by the bottom number (denominator). For example, the fraction $\frac{3}{4}$ becomes $0.75$.

2. Find 10% First: A clever trick is to find 10% of a number and then use that to find other percentages. For example, if you need to find 30% of a number, find 10% first and then multiply that by 3. If your number is $200$, then 10% is $20$. So, to find 30%, you do $20 \times 3 = 60$.

3. Use Familiar Fractions: It helps to remember some common fractions and their percentages. Here are a few:

   • $\frac{1}{2}$ = 50%
   • $\frac{1}{4}$ = 25%
   • $\frac{3}{4}$ = 75%

4. Percentage Increase or Decrease: When you want to see how much something increases or decreases by a percentage, turn that percentage into a decimal and multiply it by the whole number. For example, if a toy costs $50 and it increases by 20$20%$to a decimal ($0.20$). Then multiply:$50 \times 0.20 = 10$. Finally, add that to the original price:$50 + 10 = 60$.

These tricks can really help make working with percentages easier. With a little practice, you'll get the hang of it!
