Answer: 12
Explanation:
From the question, we are informed that Steve counts up by 4s and Jon counts up by 3s. To get the smallest number that they both say, we have to find the multiple of 3 and 4 and then choose the lowest. This will be:
Multiples of 3 = 3, 6, 9, 12, 15, 18 ...
Multiples of 4 = 4, 8, 12, 16, 20, 24 ....
We can see that the smallest is 12
