Answer:
3
Step-by-step explanation:
Note that
2 = 2 + and
1 = 1 +
We can add the whole numbers together and the 2 fractions separately, that is
2 + 1 + +
To add the fractions we require them to have a common denominator
The lowest common multiple of 7 and 4 is 28.
Multiply the numerator/denominator of the first fraction by 4
Multiply the numerator/denominator of the second fraction by 7
= 3 + +
= 3 + +
= 3 +
= 3 +
= 3
