Beginner Explanation
To solve an equation like p + 1 3/4 = 2 1/2, follow these steps:
1. Convert mixed numbers to improper fractions using n a/b = (nb + a)/b. Here, 1 3/4 = 7/4 and 2 1/2 = 5/2.
2. Rewrite the equation: p + 7/4 = 5/2.
3. Subtract 7/4 from both sides: p = 5/2 − 7/4.
4. Find a common denominator (4): 5/2 = 10/4, so p = 10/4 − 7/4 = 3/4.
5. Simplify if needed. The solution is p = 3/4.
