The answer is 240. First you see how many times 18 can go into 4 and if you can’t do that you move to the next number. How many times does 18 go into 43? 18 can fit into 43 , 2 times, so you put the 2 on top and then you put the remaining number from 43 which is 7 down and bring the 2 down. Now you have to find how many times 18 can go into 72. Which is 4 times. So u put the 4 on top next to the 2. Then you put the 0 on top next to the 24 because you can’t fit 18 into 0. So your answer is : 240
