Solve the following exercise:
21+81+41=?
To solve this problem, we'll follow these steps:
- Step 1: Find the least common denominator of 2, 8, and 4.
- Step 2: Convert each fraction to have the common denominator.
- Step 3: Perform the addition of the adjusted fractions.
- Step 4: Simplify the result if needed.
Now, let's work through each step:
Step 1: The denominators are 2, 8, and 4. The least common denominator (LCD) of these numbers is 8.
Step 2: Convert each fraction:
21=2×41×4=84
81=81 (already in the desired form)
41=4×21×2=82
Step 3: Add the fractions:
84+81+82=84+1+2=87
Step 4: The fraction 87 is already in its simplest form.
Therefore, the solution to the problem is 87.
