Answer :
Vicky uses 400 ml of lemon juice to make 700 ml of salad dressing mixed in a 4:3 ratio of lemon juice to vinegar. This is calculated by dividing the total volume by the sum of the ratio parts and then multiplying by the lemon juice parts.
Calculating the Amount of Lemon Juice
To determine how much lemon juice Vicky used, we need to first understand the ratio given. The ratio of lemon juice to vinegar is 4:3. This means for every 7 parts of the salad dressing (4 parts lemon juice + 3 parts vinegar), 4 parts are lemon juice.
Given that Vicky made 700 ml of salad dressing, we can calculate the amount of lemon juice as follows:
- Determine the total number of parts in the ratio: 4 (lemon juice) + 3 (vinegar) = 7 parts.
- Find out how many ml each part represents: 700 ml / 7 parts = 100 ml per part.
- Calculate the amount of lemon juice: 4 parts x 100 ml/part = 400 ml.
Therefore, Vicky uses 400 ml of lemon juice to make her salad dressing.
Question:-A salad dressing is made by mixing lemon juice and vinegar in the ratio 4:3 Vicky makes 700 ml of the salad dressing. How much lemon juice does she use? Give your answer in millilitres (ml).
Vicky uses 400 ml of lemon juice.
- Determine the Total Ratio Parts:
The ratio of lemon juice to vinegar is 4:3, so the total ratio parts = [tex]\(4 + 3 = 7\).[/tex]
- Find the Lemon Juice Portion:
Lemon juice part = [tex]\(\frac{4}{7}\)[/tex] of the total 700 ml.
- Calculate the Lemon Juice Volume:
Lemon juice = [tex]\(\frac{4}{7} \times 700 = 400\)[/tex] ml.
