Mark says that to divide 58 by 0.65, you only need to multiply both numbers by ten because that will give you a whole number. Jan says you need to multiply both numbers by 100. Who is correct and why?
Jan is correct because 0.65 times 10 is 6.5, which is still a decimal. 0.65 times 100 is 65, which is a whole number. Then the equation would be 5800 times 65.
