Question #293d0

Answer 1

=`47/42`

=`1 5/42`

Explanation:

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`

Answer 2

`1 5/42`

Explanation:

`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.... :)
