Lucy wants to divide 18.6 by 1.2 in order to estimate the quotient which is the best expression to use ? a: 10÷1 b: 10÷2 c: 20÷1 d: 20÷2

Option C is the best expression.

Step-by-step explanation:

We are asked to find 18.6 by 1.2.

Option A

     10÷1 = 10

     Difference = 15.5 - 10 = 5.5

Option B

     10÷2 = 5

     Difference = 15.5 - 5 = 10.5

Option C

     20÷1 = 20

     Difference = 20 - 15.5 = 4.5

Option D

     20÷2 = 10

     Difference = 15.5 - 10 = 5.5

So, the difference is minimum for option C

Option C is the best expression.
