To solve the addition of the fractions , we will first find the least common denominator.
Thus, the sum of the fractions and is .
The correct choice from the available options is .
Therefore, the solution to the problem is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
Because fractions represent parts of different wholes! means 4 parts out of 6, while means 1 part out of 8. You need the same-sized pieces (common denominator) to add them.
List multiples: 6: 6, 12, 18, 24... and 8: 8, 16, 24... The first number that appears in both lists is 24. Or use prime factorization: and , so LCM = .
Don't worry! Large denominators are normal when adding fractions. The LCM of 6 and 8 is 24, which gives us . Always check if your final answer can be simplified by finding common factors.
Check if the numerator and denominator share any common factors. For , since 19 is prime and doesn't divide 24, it's already simplified!
Yes! first, then find LCM of 3 and 8 (which is 24). You'll get: and , giving the same answer!
