Solve the following exercise:
43−61=?
To solve the problem of subtracting the fractions 43 and 61, we follow these steps:
- First, identify the least common denominator (LCD) of the given fractions' denominators. The numbers 4 and 6 have an LCD of 12.
- Next, convert each fraction to have this common denominator.
The fraction 43 is converted by determining what number we multiply 4 by to get 12 (which is 3). Thus, multiply both the numerator and the denominator by 3:
43=4×33×3=129.
The fraction 61 is converted by determining what number we multiply 6 by to get 12 (which is 2). Hence, multiply both the numerator and the denominator by 2:
61=6×21×2=122.
- Now that both fractions have the common denominator, subtract the numerators:
129−122=129−2=127.
The solution is the fraction 127.
In conclusion, the answer to this problem is 127.
