In this activity, students will learn to use a calculator to convert fractions to decimals. They will also  explore fractions equivalent to 1.
Make sure that students understand that 0.5 = 5/10 = 1/2 and that 0.75 = 75/100 = 3/4. Although question 3 is based on the use of whole numbers from 1 to 10, students could explore the basic structure of tenths, hundredths, and thousandths to give them a correct sequence. For example, 1.75 = 175/100 = 7/4 = 13/4.
Have students prove their answers on a calculator.
Question 4 highlights how important it is that students understand equivalent fractions of one whole. An example would be a pie chart divided into thirds. Help students to understand that 2/3 means two of the parts that make one whole and 3/3 means three of the three parts that make one whole, so 3/3 is the same as one.
