Answer:
![\frac{10}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B21%7D)
Step-by-step explanation:
The LCM of 14, 21 and 6 is 42
We require to change the fractions to fractions with a denominator of 42
+
+ ![\frac{1(7)}{6(7)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%287%29%7D%7B6%287%29%7D)
=
+
+
← add the numerators, leaving the denominator
= ![\frac{9+4+7}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B9%2B4%2B7%7D%7B42%7D)
=
← divide both values by 2
=
← in simplest form
Simplify the radical by breaking down the radicand up into a product of known factors.
