Answer to Question 1

4

Rationale 1: Set up the equation so that 0.20 is being divided into 0.35. Move the decimal point 2 spaces to the right. Divide 20 into 35. Place the number 1 above the number 5. The remaining value to divide by 20 is now 15. Add a 0 to 15 and divide 20 into 150. Place the number 7 in the first place after the decimal point. The remaining value to divide by 20 is now 10. Add a 0 to the 10 and divide 20 into 100. Place the number 5 in the second space after the decimal point.

Answer to Question 2

3

Rationale 1: The number of spaces after the decimal point is 2; therefore the denominator for the conversion of 0.85 to a fraction is 100. The fraction would be 85/100. When reducing to the smallest terms, divide both the numerator and denominator by 5 to determine the fraction 17/20.
