Answer:
17/12
Step-by-step explanation:
To add fractions, the denominators have to be the same. 12 is the least common multiple between 3 and 4 so we should multiply the numerator and denominator of both fractions with a number that will make the denominator 12. Then, add the numerators.
[tex] - \frac{1}{3} + \frac{7}{4} [/tex]
[tex] - \frac{1 \times 4}{3 \times 4} + \frac{7 \times 3}{4 \times 3} [/tex]
[tex] - \frac{4}{12} + \frac{21}{12} [/tex]
[tex] \frac{17}{12} [/tex]
