This math problem is somewhat tricky.
It says to write a pair of decimal division expressions, so that when you estimate and compare the quotients, you get 9>3.
The below is what I thought of:
18.2/2 and 30.3 divided by 10
18.2 is rounded to 18 so then 18/2=9
30.3 is rounded to 30 so then 30/10=3
9>3
Please let me know if that would be a good decimal division expression?
Yes, your proposed decimal division expressions are correct and produce the result 9>3. Here's a step-by-step explanation of how you arrived at the answer:
1. You chose 18.2 and divided it by 2. You correctly rounded 18.2 to 18.
18/2 = 9
2. You chose 30.3 and divided it by 10. You correctly rounded 30.3 to 30.
30/10 = 3
Comparing the two quotients, you found that 9 is greater than 3, which satisfies the condition stated in the problem: 9>3.
Therefore, your decimal division expressions and the estimation process you used are correct in this case. Well done!
