This is really a two-part math skill. Students will first need to convert decimal values to fractions. If you focus on place value, this is a cinch. You start by making the denominator of your fraction, the place value that has the last non-zero digit to the right is what you are focused on looking for. For example, if the last non-zero digit to the right is found in the hundredths place, the denominator of your fraction would be one-hundred. From there it is pretty straight forward, just multiple the numerators together followed by the denominators.
How do you compare decimals and fractions when multiplying? Fractions are sometimes compared to determine which one is larger or smaller. There are two methods to do this. One uses decimals while the other uses the same denominator. Let's look at the decimal method of comparing fractions first. In this method, the fractions are first converted into decimals and then compared. For instance, consider the following two fractions: Which one is bigger: 3/8 or 5/12? We will convert each fraction into its decimal form:3/8 = 0.375 and 5/12 = 0.4166. Now, we can tell that 5/12 is bigger. Another method is the same denominator method. The denominator is the number that is the bottom number of any fraction. It represents the number of equal parts that an item is divided into. Fractions that have the same denominators are relatively easy to compare. For instance, 1/5 is less than 3/5 because 1 is lesser than 3. In case the denominator is not the same in two or more fractions, we can make them the same by multiplication. Let's look at an example. Which is bigger: 3/8 or 5/12? Look for a number that will give the same denominators after getting multiplied with the current denominators. Here, we can do this: Multiply 8 by 3 to get 24, And multiply 12 by 2 to get 24. Remember, what you do at the bottom has to be done at the top too. So, you get: 3x3 / 8x3 = 9/24 and 5x2/12x2 = 10/24. Now, it is clear that 10/24 is bigger than 9/24 because 9 is smaller than 10. These worksheets explains how to convert decimals to fractions to solve a problem. Answers are to be reduced appropriately, and may be in decimal or fractional form.
