= $47/42$

= $1 5/42$

When adding or subtracting fractions we need to find a common denominator. For 6 and 7, the lowest common denominator is 42.

Make equivalent fractions.

$2/7 + 5/6" "rarr (2xx6)/(7xx6) + (5xx7)/(6xx7)$

= $(12+35)/42$

= $47/42$

= $1 5/42$

$1 5/42$

$color(blue)(2/7+5/6$

If we need to add fractions, we should have the same denominator.
So, we need to find the least common denominator of $7 and 6$

It is $42$

Convert the initial fractions

$rarr2/7+5/6$

$rarr(2xx6)/(7xx6)+(5xx7)/(6xx7)$

$rarr12/42+35/42$

$rarr(12+35)/42$

$rarr47/42$

$color(green)(rArr1 5/42$

Hope this helps.... :)
