Fractions Estimating (Estimating Sums and Differences of Fractions Calculator)

The process of Estimating sums and differences for positive proper fractions, n/d (numerator/denominator), where n ≤ d and 0 ≤ n/d ≤ 1. By using Rounding, you can attain the estimated answers when adding or subtracting proper fractions. So, follow the steps given here and do fractions estimation easily by hand.

• First, take the input proper fractions and round to 0, 1/2, or 1 to get the estimated fractions.
• Here, you can round the fractions to the nearest 1/2, 1/4, and 1/8.
• suppose, if you consider 1/2 as the nearest, then round the inputs nearest to 1/2.
• Later, do the required operation of the rounded values like addition or subtraction and get the estimated fraction result.
• That's it! now you have an output for the estimating sum of fractions or estimating difference of fractions.

Estimating operations on proper fractions can be performed more accurately by a human than a calculator. But Onlinecalculator.guru provided Free online Fractions Estimating Calculator helps you to make your calculations easy & accurate.

Example 1

Question: Estimate the sum of Fractions 2/4 + 2/5 to the nearest 1/2?

Solution:

Given fractions equation is 2/4 + 2/5

Now, you have to estimate the fractions sum value by rounding to the nearest 1/2 for each input

⇒ 1/4 ≤ 2/4 ≤ 3/4 so round it to 1/2.

⇒ 1/4 ≤ 2/5 ≤ 3/4 so round it to 1/2.

Later, consider the rounded values & do addition operation to estimate the sum of fractions:

⇒ 1/2 + 1/2 = 1

Thus, the estimated value for the sum of given fractions 2/4 + 2/5 is 1. 

Example 2

Question: Estimate the difference of Fractions 5/7 - 2/6 to the nearest 1/4?

Solution:

Given fractions equation is 5/7 - 2/6

Now, estimate the fractions difference value by rounding to the nearest 1/4 for each input

⇒ 5/8 ≤ 5/7 < 7/8 so round it to 3/4.

⇒ 1/8 ≤ 2/6 < 3/8 so round it to 1/4.

Later, consider the rounded values and perform the subtraction operation to estimate the difference of fractions:

⇒ 3/4 - 1/4 = 1/2

Thus, the estimated value for the difference of given fractions 5/7 - 2/6 is 1/2. 

Example 3

Question: Estimate the sum of fractions 4/5 + 5/7 to the nearest 1/8?

Solution:

Given estimated fractions equation is 4/5 + 5/7

Now, you have to estimate the fractions sum value by rounding to the nearest 1/8 for each input

⇒ 11/16 ≤ 4/5 < 13/16 so round it to 6/8.

⇒ 11/16 ≤ 5/7 < 13/16 so round it to 6/8.

Later, consider the rounded values and perform the summation operation to get the estimated sum fraction value:

⇒ 6/8 + 6/8 = 1 1/2

Thus, the estimated value for the sum of given fractions 4/5 + 5/7 is 1 1/2.
