Question

there are 3 red marbles in a bag and there are 4 blue marbles in the bag which of the following is a possible total number of marbles?

Answer 1

3+4 is 7. That means any multiplies of 7 can be a possible total number of marble. For example, 14 is a multiple of 7 and can also be a possible number; 3*2=6, 4*2=8, 6+8=14!
Hope that helps!!!
