Answer 2

Answer:
`4\ (1)/(12)`

Explanation:

We can convert the Mixed numbers to Improper fractions:

- Multiply the the whole number part by the denominator of the fraction.

- Add the product obtained and the numerator of the fraction.

- The sum obtained will be the new numerator.

- The denominator does not change.

Then:

`(1\ (1)/(3))+(2\ (3)/(4))=((1*3)+1)/(3)+((4*2)+3)/(4)=(4)/(3)+(11)/(4)`

Now find the Least Common Denominator (LCD) and add the fractions:

`=(16+33)/(12)=(49)/(12)`

Finally, you can convert back to Mixed numbers:

-Divide the numerator by the denominator.

- Write the whole number.

- The remainder will be the new numerator.

- The denominator does not change.

Then:

`=4\ (1)/(12)`
