Solve the following exercise:
73−31=?
To solve this problem, we'll follow these steps:
- Step 1: Identify the fractions and denominators involved.
- Step 2: Find a common denominator for the two fractions.
- Step 3: Convert each fraction to an equivalent fraction with the common denominator.
- Step 4: Subtract the numerators and simplify the result.
Let's perform each of these steps:
Step 1: We have the fractions 73 and 31.
Step 2: Find a common denominator. The denominators are 7 and 3, so the common denominator will be 7×3=21.
Step 3: Convert each fraction:
- For 73, multiply both numerator and denominator by 3 to get 7×33×3=219.
- For 31, multiply both numerator and denominator by 7 to get 3×71×7=217.
Step 4: Subtract the numerators:
219−217=219−7=212.
Simplify if necessary: Here, 212 is already in its simplest form.
Therefore, the solution to the problem is 212.
