To order numbers of different types (percentages, decimals, fractions), it is easiest to convert them all into a single, consistent format. Let's convert them all to decimals.
1. **80%**: The word "percent" means "out of 100". So, 80% is 80/100, which is 0.8.
2. **0.7**: This is already in decimal form.
3. **3/4**: To convert a fraction to a decimal, you can find an equivalent fraction with a denominator of 100. 3/4 is equivalent to 75/100, which is 0.75.
Now we have the three numbers as decimals: 0.8, 0.7, and 0.75.
We can now easily order them from smallest to largest:
0.7 is the smallest.
0.75 is next.
0.8 is the largest.
Finally, we write the numbers in their original forms in this order: 0.7, 3/4, 80%.
