Question

Dakota makes a salad dressing by combining 6 1/2 fluid ounces of oil and 2 3/8 fluid ounces of vinegar in a jar. She then pours 2 1/4 fluid ounces of the dressing into her salad. How much dressing remains in the jar?

Answer 1

`6 (1)/(2) + 2 (3)/(8) = \\ (13)/(2) + (19)/(8) = \\ (52)/(8) + (19)/(8) = \\ (71)/(8)`

`(71)/(8) - 2 (1)/(4) = \\ (71)/(8) - (9)/(4) = \\ (71)/(8) - (18)/(8) = \\ (53)/(8)`

`(53)/(8) = 6 (5)/(8)`
