Answer:

r + 1

Step-by-step explanation:

Combine like terms. Add the constants together and add the terms with the variable r together. In order to add fractions, keep the common denominator and add only the numerators together. Then, simplify, and divide the numerator by the denominator if the result is a whole number.

This gives the following answer:

$\frac{1}{3} r+\frac{1}{4} +\frac{2}{3} r+\frac{3}{4} \\=\frac{1}{3} r+\frac{2}{3} r+\frac{1}{4} +\frac{3}{4}\\=\frac{3}{3} r+\frac{4}{4} \\=r+1$
