Question

Jan has 10 dolls. Kat has 7 dolls. choose yes or no to show if the equation can be used to find how many fewer dolls Kat has than Jan.

10-7=3 yes or no

3+7=10 yes or no

10+7=17 yes or no

7+3=10 yes or no

Answer 1

10-7 = 3 yes. Pretty simple stuff for a middle schooler...

Answer 2

The answer is 10-7. The reason is that if Jan has 10 and she has 7, they want to know fewer which means less than as subtracting. So basically you would do 10-7 and that is 3. Also you can tell by the question that its 10-7. Hope it helps!
