Solve the following exercise:
124+31+61=?
To solve the problem, we start by finding the least common denominator (LCD) for the fractions 124, 31, and 61.
The denominators are 12, 3, and 6. We need to find the smallest number that is a multiple of each of these numbers. The LCD of 12, 3, and 6 is 12.
Next, we convert each fraction to have this common denominator:
- 124 already has 12 as the denominator.
- 31 can be converted to have 12 as the denominator by multiplying both the numerator and the denominator by 4: 31=3×41×4=124.
- 61 can be converted to have 12 as the denominator by multiplying both the numerator and the denominator by 2: 61=6×21×2=122.
Now, we simply add these fractions:
124+124+122=124+4+2=1210.
Therefore, the solution to the problem is 1210.
