64+81=
To solve the addition of the fractions 64+81, we will first find the least common denominator.
- The denominators of the fractions are 6 and 8. To add these fractions, we need a common denominator.
- Calculate the least common multiple (LCM) of 6 and 8:
- Prime factorization of 6: 6=2×3.
- Prime factorization of 8: 8=23.
- The LCM will take the highest power of each prime that appears in these factorizations: 23×3=24.
- Convert each fraction to an equivalent fraction with 24 as the denominator:
- Convert 64: Multiply both the numerator and denominator by 4 (since 624=4): 6×44×4=2416.
- Convert 81: Multiply both the numerator and denominator by 3 (since 824=3): 8×31×3=243.
- Now, add these two fractions:
- 2416+243=2416+3=2419.
Thus, the sum of the fractions 64 and 81 is 2419.
The correct choice from the available options is 2419.
Therefore, the solution to the problem is 2419.
