Question

How do you evaluate `7 6/7 +4 5/7`?

Answer 1

`12 4/7`

Explanation:

`"note that "7 6/7=7+6/7`

`"and "4 5/7=4+5/7`

`rArr7 6/7+4 5/7`

`=color(red)(7)+6/7color(red)(+4)+5/7`

`=(color(red)(7+4))+6/7+5/7`

`"since fractions have a "color(blue)"common denominator"`
`"add the numerators leaving the denominator"`

`=11+(6+5)/7`

`=11+11/7=11+1 4/7=12+4/7`
