Question 10 • Common Core Math 7 A-IC
To divide 73.85 by 4.1 using whole-number division, first make the divisor a whole number by moving its decimal one place to the right: 4.1 becomes 41. To keep the quotient unchanged, move the dividend’s decimal one place as well, which is the same as multiplying both numbers by 10. Therefore, the first step is to multiply the divisor and dividend by 10.
