Let’s solve each problem step by step. We’re converting decimals to fractions.
How to convert a decimal to a fraction:
1. Write the decimal as a fraction over 1 (like this: decimal/1).
2. Multiply top and bottom by 10, 100, 1000… depending on how many digits are after the decimal point.
- 1 digit → multiply by 10
- 2 digits → multiply by 100
3. Simplify the fraction if possible.
