Question

duncan has 9 gumballs. marie has 3 fewer gumballs than duncan. write an expression that shows how many gumballs marie has.

Explanation:

Step1: Identify Duncan's gumballs

Duncan has 9 gumballs, so we start with the number 9.

Step2: Determine Marie's gumballs

Marie has 3 fewer gumballs than Duncan. To find how many Marie has, we subtract 3 from Duncan's number of gumballs. So the expression is $9 - 3$.

Answer:

The expression is $9 - 3$ (and the value is 6, but the expression as per the problem is $9 - 3$).
