Trevors baseball card collection consists of 228 cards. this is 4 times as many cards as ming has. how many baseball cards are in mings collection'

57

Step-by-step explanation:

If Trevor has 4 times more cards then Ming and Trevor has 228 cards you would divide 228 by 4 to get the number of cards ming has.

228 divided by 4 is 57

The quotient is the result of dividing,, so this means that we need to divide 15 by the product of 2 times x. The product of something means that we need to multiply 2 by x and then divide that answer by 15. This means that our equation will look like the following:
15 ÷ (2 × x)
Since we cannot do much with this problem,, all we need to do is write the division as a fraction in order to get our final answer.
