Solve the following exercise:
21+61+123=?
To solve the given problem, let's follow these steps:
- Step 1: Find the Least Common Denominator (LCD)
The denominators are 2, 6, and 12. The least common multiple (LCM) of these numbers is 12.
- Step 2: Convert each fraction to have the common denominator of 12
Here is how to convert each fraction:
- 21 becomes 2×61×6=126
- 61 becomes 6×21×2=122
- 123 is already with denominator 12, so it remains 123.
- Step 3: Add the fractions
Now add the equivalent fractions:
126+122+123=126+2+3=1211.
Therefore, the solution to the problem is 1211.
