Answer: B.Start with 45 tiles and separate them into 15 same-sized groups.
Step-by-step explanation:
To evaluate 45 divided by 15 using integer tiles .
Here dividend = 45
Divisor =15
First we need to start with the dividend number, therefore we have to start with 45 tiles .
For the second step we need to separate them into same sized group and the size of the group must be same as the divisor.
Thus, we need to separate 45 tiles into 15 same-sized groups, we will get 3 groups which will be the answer.
Therefore, B is the right option.
