What are the steps for using integer tiles to evaluate the expression 45 divided by 15
a. start with 15 tiles and separate them into 3 same-sized groups.
b. start with 45 tiles and separate them into 15 same-sized groups.
c. assemble 45 groups of 3 tiles each.
d. assemble 45 groups of 15 tiles each.

 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.

hi, i am not sure about this one but i think its d,

hope this !

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
