Question 486144
54 is 5 tens + 4 ones.
5 / 3 is 1 ten with 2 tens left over.
2 tens + 4 ones is 24 ones.
24 / 3 = 8 (ones).
So the answer is 1 ten and 8 ones = 18.
Note that all the divisions are from the single digit mult table, so that using it and the distributive property (and power notation of numbers) is all one needs.
