A common denominator for these fractions is ____.
Whose recipe has a smaller ratio of vinegar to oil? ____.

Answer 1

we know that
a) Paula’s recipe calls for 8 ounces of oil for every 3 ounces of vinegar
ratio of vinegar to oil-----> 3 ounces/8 ounces-----> 0.375


b) Carlo’s recipe has 1 ounce of vinegar for every 4 ounces of oil
ratio of vinegar to oil-----> 1 ounces/4 ounces---> 0.25

1) Whose recipe has a smaller ratio of vinegar to oil?
0.25< 0.375
so
Carlo’s recipe < Paula’s recipe

the answer Part 1) is
Carlo’s recipe has a smaller ratio of vinegar to oil--- > 0.25

Part 2) Paula’s dressing ratio of vinegar to oil written as a fraction is 3/8

Part 3)Carlo’s dressing ratio of vinegar to oil written as a fraction is 1/4 (is equal to 2/8)

Part 4) A common denominator for these fractions is 8
