Answer:
16
Step-by-step explanation:
a, 10
Group of 10 23s gives us 230. This is so because of you arrange 23 in groups, you would need to arrange it in 10 places, to get 230.
b, 6
Group of 6 23s gives 138. Again, like stated above, arranging 23 in 6 places ends up giving us a total of 138.
Adding both together, we have
10 + 6 = 16.
This means our answer is 16. And this is rightly so. Dividing 368 by 23 gives us 16 exactly. So, 16 is the answer.
