1. Solving Math problem 4 on page 114 from textbook exercise 1
Solution method:
Method for simplifying fractions:
- Step 1: Analyze whether both the numerator and denominator of the fraction are divisible by a natural number greater than 1
- Step 2: Divide both the numerator and denominator of the fraction by that number
- Step 3: Repeat the above two steps until the fraction is simplified.
=> A simplified fraction (irreducible) is a fraction where the numerator and denominator are not both divisible by a natural number greater than 1.
