What could you add to 23 to make is divisible by 10...2..5..?
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
