Answer :
To find out how much lemon juice Vicky uses, we need to work with the given ratio and the total amount of salad dressing.
1. Understand the Ratio: The ratio of lemon juice to vinegar is 4:3. This means for every 4 parts of lemon juice, there are 3 parts of vinegar.
2. Determine Total Parts: Add the parts of lemon juice and vinegar in the ratio to get the total number of parts in the mixture:
- Lemon juice parts = 4
- Vinegar parts = 3
- Total parts = 4 + 3 = 7 parts
3. Calculate the Amount of Each Part: Vicky makes a total of 700 ml of the salad dressing. Each part of the mixture is calculated by dividing the total amount by the total number of parts in the ratio:
- Amount per part = Total amount / Total parts = 700 ml / 7 parts = 100 ml per part
4. Calculate the Amount of Lemon Juice: Since the amount of lemon juice corresponds to 4 parts, multiply the amount per part by the number of lemon juice parts:
- Lemon juice = 4 parts × 100 ml per part = 400 ml
So, Vicky uses 400 ml of lemon juice in her salad dressing.
