a salad dressing is made my mixing yougurt and mayonaise in the ratio 3:5.jeff makes 800ml of the salad dressing,how much yougurt does she use

To solve this problem, we use the given ratio of yogurt to mayonnaise, which is \(3:5\). This means that for every 3 parts of yogurt, there are 5 parts of mayonnaise.

### Steps:

1. **Total parts of the mixture**: The total parts of the mixture are \(3 + 5 = 8\) parts.
2. **Amount of yogurt**: Since the yogurt is 3 parts out of the total 8 parts, the fraction of yogurt in the mixture is:

   \[
   \text{Fraction of yogurt} = \frac{3}{8}
   \]

3. **Amount of yogurt in 800 ml**: To find the amount of yogurt in 800 ml of dressing, multiply the total amount by the fraction of yogurt:

   \[
   \text{Amount of yogurt} = \frac{3}{8} \times 800 = 300 \, \text{ml}
   \]

### Conclusion:
Jeff uses **300 ml** of yogurt to make the 800 ml of salad dressing.

Here are 5 related questions:
1. How much mayonnaise does Jeff use in the 800 ml of dressing?
2. If Jeff makes 1200 ml of salad dressing, how much yogurt does he use?
3. If the ratio of yogurt to mayonnaise changes to 4:5, how much yogurt would be needed for 800 ml?
4. What is the amount of yogurt in 600 ml of salad dressing with the same ratio?
5. If Jeff only uses 240 ml of yogurt, how much mayonnaise does he need to keep the 3:5 ratio?

**Tip**: Ratios can always be simplified by dividing both terms by their greatest common divisor (GCD).

A salad dressing is made by mixing yogurt and mayonnaise in the ratio 3:5. Jeff makes 800ml of the salad dressing, how much yogurt does he use?
