As an AI developed by OpenAI, I don't have access to specific test answers or pre-determined solutions to specific tests or assignments.
However, I can provide you with a general explanation of how to solve problems involving operations with fractions. This will help you understand the concepts and strategies you can use to solve questions on your test.
To solve problems involving operations with fractions, such as addition, subtraction, multiplication, and division, you can follow these steps:
1. Addition and Subtraction:
- Make sure the denominators (the numbers at the bottom of the fractions) are the same. If they are not the same, find a common denominator by multiplying the two denominators together.
- Once you have a common denominator, add or subtract the numerators (the numbers at the top of the fractions) while keeping the denominator the same.
- Simplify the fraction if necessary by dividing both the numerator and the denominator by their greatest common divisor.
2. Multiplication:
- Multiply the numerators together to find the new numerator.
- Multiply the denominators together to find the new denominator.
- Simplify the resulting fraction if necessary.
3. Division:
- Multiply the first fraction by the reciprocal (or inverse) of the second fraction. The reciprocal of a fraction is found by swapping the numerator and the denominator.
- Once you have the reciprocal, perform the multiplication between the first fraction and the reciprocal.
- Simplify the resulting fraction if necessary.
These steps should help you perform the basic operations with fractions. Remember to always simplify your final answers if possible.
It's important to practice solving various problems involving fractions to improve your understanding of the concepts and build your problem-solving skills.
