Step-by-step solution for: Printable primary math worksheet for math grades 1 to 6 based on ...
To solve the problems involving the addition of mixed numbers, we need to follow these steps:
1. Convert mixed numbers to improper fractions (if necessary).
2. Find a common denominator for the fractions.
3. Add the fractions and then add the whole numbers.
4. Simplify the result to its lowest terms.
Let's solve each problem step by step.
---
1. Convert to improper fractions:
- \( 3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{15}{4} \)
- \( 2 \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2} \)
2. Find a common denominator (LCM of 4 and 2 is 4):
- \( \frac{5}{2} = \frac{5 \times 2}{2 \times 2} = \frac{10}{4} \)
3. Add the fractions:
- \( \frac{15}{4} + \frac{10}{4} = \frac{25}{4} \)
