Question

A salad dressing is made by mixing oil and vinegar in the ration 3:1.

a) How much oil should be mixed with 35ml of Vinegar?
b) Sam mixes 60ml of oil with 40ml of vinegar. Is this an equivalent ratio to the one given above? Demonstrate your answer by writing it in simplest form

Answer 1

[AI-generated answer — Bot GPT 3.5]

a) To find how much oil should be mixed with 35ml of vinegar in a 3:1 ratio, we first need to find the total parts in the ratio, which is 3 + 1 = 4 parts.

Since the ratio is 3:1, we divide the total parts by the given ratio parts:
Oil = (3/4) x 35ml = 26.25ml

So, 26.25ml of oil should be mixed with 35ml of vinegar.

b) To determine if Sam's ratio of 60ml oil to 40ml vinegar is equivalent to the given 3:1 ratio, we need to simplify it to the same form.

60ml : 40ml = 60/20 : 40/20 = 3:2

The ratio 3:2 is not equivalent to the given ratio of 3:1, so Sam's mixture is not in the same ratio as the original one.
