what is the distributive property of 15+45

Question

My math homework says 15+45 and another sum and i know its distributive property what's the answer i"m stuck HELP!!!!!!

Answer 1

Note that 15 is a common factor of 15 and 45:

 

15 = 1 x 15

45 = 3 x 15

 

So you can write 15 + 45 as

 

15 + 45 = 15 + (15 x 3)

 

Factor out the 15 and get

 

15 + 45 = 15 (1 + 3)
