Dakota makes salad dressing by combining 4 1/3 fluid ounces of oil and 3 3/8 fluid ounces of vinegar in a jar. She then pours 3 1/4 fluid ounces of the dressing onto her salad. How much dressing remains in the jar?

9514 1404 393

  4 11/24 fl oz

Step-by-step explanation:

The volume of dressing Dakota made is ...

  4 1/3 + 3 3/8 = (4 +3) +(1/3 +3/8) = 7 + (8/24 +9/24) = 7 17/24 . . . ounces

After using 3 1/4 ounces, the remaining amount is ...

  7 17/24 - 3 1/4 = (7 -3) +(17/24 -6/24) = 4 11/24 . . . . ounces

4 11/24 fluid ounces of dressing remains in the jar.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
