unit 5 lesson 6 math quick check answers
1. Is there a common denominator for 1/6 and 1/3? Why or why not?
No, there is no common denominator because the denominators are already different.
2. Which is greater, 2/3 or 3/4?
To compare fractions, we need to find a common denominator. In this case, the common denominator for 2/3 and 3/4 is 12. When we convert both fractions to have a denominator of 12, we get 8/12 for 2/3 and 9/12 for 3/4. Therefore, 3/4 is greater than 2/3.
3. If you divide a number by 3 and then multiply the result by 4, does it matter if you multiply by 4 first and then divide by 3? Why or why not?
It does not matter because multiplication and division are inverse operations, meaning the order in which they are applied does not change the final result.
