Solve the following exercise:
52+62=?
To solve the problem 52+62, we need a common denominator:
- Step 1: Find the least common multiple (LCM) of the denominators 5 and 6. The LCM of 5 and 6 is 30.
- Step 2: Rewrite each fraction to have the denominator 30:
- For 52: Multiply the numerator and denominator by 6 (since 5×6=30). This gives 5×62×6=3012.
- For 62: Multiply the numerator and denominator by 5 (since 6×5=30). This gives 6×52×5=3010.
- Step 3: Add the two fractions: 3012+3010=3022.
- Step 4: Simplify the resulting fraction. Since 3022 is already in simplest form, no further simplification is necessary.
Therefore, the sum of 52 and 62 is 3022, which corresponds to choice 4.
