Question

An algorithm for dividing decimals states you cannot have a decimal point in the divisor. To remove the decimal, multiply both factors by a factor of 10. For example, 26 ÷ 1.3 becomes 260 ÷ 13 = 20. 20 is also the solution for 26 ÷ 1.3.
Which number sentence correctly models this algorithm for 75 ÷ 2.5?

A. 2.5 ÷ 750 = 300
B. 75 ÷ 250 = 0.3
C. 750 ÷ 25 = 30
D. 75 ÷ 25 = 3

Answer 1

C., because 75 with the decimal moved to the right one space is 750 and 2.5 would be 25
