Estimating Sums and Differences (Fractions) Worksheets
How Do You Estimate Sums and Difference Between Fractions? Estimation is one of the valuable skills and is commonly used in our daily lives. Doing the estimation of whole numbers and integers is much easier than performing the same at fractions. We can estimate, add or subtract numbers like 4, 12, 344 quickly, but estimating numbers like 4/5 or 9/11 poses a challenge for us. Understanding how to perform addition and subtraction on fractions can save us time and also get us the approximate answer. To ease your estimation, remember the tip for rounding off the fraction to their nearest 1/2. As per this rule, the fractions would be rounded off to 0, 1/2, or 1. Any fraction with a value less than 1/4 will be rounded off to 0. Fractions that are equal to or greater than 1/4 and less than or equal to 3/4 will be rounded off to 1/2. Every fraction with a value greater than 3/4 will be rounded off to 1. You can also solve the problem without converting them to their nearest ½ values. For instance, you are given the fraction 9/16 and 5/12. First, you would convert each fraction to achieve the same denominators. 9/16 would be converted into 27/48, and 5/12 would be converted into 20/48. Then add or subtract both the values 27/48 + 20/ 48 = 47/48. Subtraction is carried out in the same way. 27/48  20/48 = 7/48.
