thanks miss sue that was very helpful.
To add, subtract, multiply, and divide fractions, follow the steps below:
1. Adding fractions:
- Make sure the denominators (the bottom numbers) are the same. If they are not, find a common denominator by multiplying the denominators together.
- Once the denominators are the same, add the numerators (the top numbers) together and keep the denominator the same.
- Simplify the fraction, if needed, by reducing it to its lowest terms.
2. Subtracting fractions:
- Like addition, make sure the denominators are the same.
- Subtract the numerators while keeping the denominator the same.
- Simplify the result, if necessary.
3. Multiplying fractions:
- Multiply the numerators together to get the new numerator.
- Multiply the denominators together to get the new denominator.
- Simplify the result, if needed.
4. Dividing fractions:
- Invert (flip) the second fraction (divisor) and turn division into multiplication.
- Multiply the first fraction (dividend) by the inverted second fraction.
- Simplify the result, if necessary.
Remember to always simplify fractions by reducing them to their lowest terms whenever possible.
If you need help with specific examples, please provide the fractions you want to work with, and I can guide you step by step.
