Question
Jacob found some hermit crabs. Justin found 15 hermit crabs. They now have 23 hermit crabs. How many did Jacob find?
Which equation models the problem?
- 15 + 23 = ?
- ? + 15 = 23
- 23 + 15 = ?
- ? + 23 = 15
Hint:
We have to find the correct equation according to the question. Here Jacob find some crabs and Justin finds 15 crabs so, the total no. of crabs should be the sum of crabs they both found.
The correct answer is: ? + 15 = 23
The equation that models the situation is ? + 15 = 23
NO. of hermit crabs Jacob found = ?
NO. of hermit crabs Justin found = 15
S0 total hermit crabs =? + 15 = 23
