Task with Fractions for 5th Grade

To create a task involving fractions for 5th graders, we can use the following information from the search results:

Task Description: - Problem 1: Calculate the sum of fractions: \( \frac{25}{40} + \frac{55}{120} \). - Problem 2: Subtract fractions: \( \frac{150}{35} - \frac{115}{120} \). - Problem 3: Calculate the percentage: What is 25% of 40?- Problem 4: Solve the equation: \( \frac{8}{10} = \frac{x}{100} \).

Solution: 1. Problem 1: - \( \frac{25}{40} + \frac{55}{120} = \frac{25}{40} + \frac{11}{24} = \frac{120}{192} + \frac{80}{192} = \frac{200}{192} = 1 \frac{8}{192} \) or \( 1 \frac{1}{24} \).

2. Problem 2: - \( \frac{150}{35} - \frac{115}{120} = \frac{30}{7} - \frac{115}{120} = \frac{14400}{3360} - \frac{2805}{3360} = \frac{11595}{3360} = 3 \frac{1515}{3360} \) or \( 3 \frac{505}{1120} \).

3. Problem 3: - 25% of 40 is 10.

4. Problem 4: - \( \frac{8}{10} = \frac{x}{100} \) can be solved as \( 8 \times 10 = x \times 100 \) which simplifies to \( 80 = 100x \). Solving for \( x \), we get \( x = \frac{80}{100} = 80% \).

By incorporating these problems, we can create a comprehensive task involving fractions and percentages for 5th graders.
