Answer:

To make a high estimate for the sum of two fractions, find the commnon denominator and add them.

Step-by-step explanation:

To make a high estimate for the sum of two fractions in a word problem, rhe following steps are required.

Let the two fractions be represented as [tex]\frac{x}{y}[/tex] and [tex]\frac{a}{b}[/tex]

To perfrom the operation  [tex]\frac{x}{y}[/tex]  + [tex]\frac{a}{b}[/tex]

Step 1 : Check if the denominators of the fraction are same. If so then, then add the numerators directly by keeping the same denominator.

Step 2: If the denominators are different, then find the common denominator between the fractions and multiply them accordingly. Then perform the addition operation.

A high estimate of the sum of fractions is gotten by finding a common denominator of the fractions, and then sum them up afterwards.

Take for instance, the following sum of fractions:

[tex]\mathbf{\frac{1}{2} + \frac{5}7}[/tex]

Express 1/2 and 5/7 as fractions of the same denominators

[tex]\mathbf{\frac{1}{2} + \frac{5}7 = \frac{7}{14} + \frac{10}{14}}[/tex]

Take LCM

[tex]\mathbf{\frac{1}{2} + \frac{5}7 = \frac{7 + 10}{14}}[/tex]

Add the expressions on the numerator

[tex]\mathbf{\frac{1}{2} + \frac{5}7 = \frac{17}{14}}[/tex]

So, a high estimate of the sum of fractions is gotten by adding the fractions after finding a common denominator.
