Hey there! :)

Answer:

29/28.

Step-by-step explanation:

Starting with:

$\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =$

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =$

Add the fractions:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}$

Therefore, the fractions sum up to 29/28.
