Answer:
If Justin give's each of his children 7 one dollar bills, He will have 2 one dollar bill remaining
Explanation:
since he has 3 children he have to divide 23 by 3 so we count until we get a number close to 23 but not greater because we have to subtract that number from 23
3.6.9.12.15.18.21.24.27.30.
Now that we found our number closest to 23 without going greater than 23 we subtract it from 23
23
- 21
2
so that's how we got the remaining amount of money but we count how many time's we multiplied to get 21, that's 7 which is the amount each children gets.
I hope this helps :)
