Solve the following exercise:
43−93=?
To solve this problem, we'll follow these steps:
- Step 1: Find a common denominator for the fractions 43 and 93.
- Step 2: Convert each fraction to have this common denominator.
- Step 3: Subtract the numerators while keeping the common denominator.
- Step 4: Simplify the resultant fraction if possible.
Now, let's work through each step:
Step 1: The denominators of the fractions are 4 and 9. The least common multiple of 4 and 9 is 36. Therefore, 36 will be our common denominator.
Step 2: Convert 43 and 93 to have a denominator of 36:
43×99=3627 and 93×44=3612
Step 3: Now, subtract the fractions:
3627−3612=3615
Step 4: Simplify 3615:
Both 15 and 36 can be divided by their greatest common divisor, which is 3. Dividing both the numerator and denominator by 3, we get:
36÷315÷3=125
Therefore, the solution to the problem is 125.
