Students should be able to convert fractions to decimals, decimals to fractions, percents to decimals, decimals to percents and so on. Although the calculator makes these computations easy, first and foremost, students should understand the math behind the calculator functions. These worksheets require students to perform the calculation manually and to check with the calculator. (For a calculator, you simply divide the top number by the bottom number.) However, that's simply the computation and not the number. Use visuals (pizza works great) to help students understand the actual math behind the concept.

A quick method to do so is to find an equivalent fraction with a denominator of 10, 100, 1000, 10,000, etc.

15/20 = 75/100 which means the decimal for 15/20 which is also 3/4 will be 0.75
