• Can you also compare fractions by rewriting them as decimals?
• Yes - sometimes that is an easier.
For example if you have 7/10 and 3/4 and you know that 7/10 = 0.7 and 3/4 = 0.75, so 3/4 is bigger.
Sometimes it is harder. For example: you wouldn't want to change 3/7 to a decimal, if you didn't have to.
• i agree can you also compare fractions by rewriting them as decimals
• Yes, converting to decimals is one method of comparing fractions. This method is easiest when the denominators are “nice” (for example, 2, 4, 5, 8, 10, 20, etc).

Have a blessed, wonderful day!
