question 1: eight goes into the number 52 six times, so that is what goes in the box to the left of “r”. 8 x 6 = 48, so that is what goes into the two boxes below 52. do 52-48 which equals 4, meaning that 4 is what goes to the right of “r”.
question 2: five goes into forty-one 8 times, so put the 8 to the left of “r”. multiply 5 x 8 = 40, and put the 40 below the 41. subtract 41-40= 1, meaning the 1 is what you put to the right of “r”.
question 3: six goes into twenty-seven 4 times, so put the four above the 27. multiply 6 x 4 = 24, so put the 24 below the 27. subtract 27-24= 3, meaning 3 is the number that goes to the right of “r”
