Question

determine if each problem is worked correctly and, if not, find the mistake. a solution of water and bleach must be mixed in a 4:1 ratio. if you need 4 cups of the solution how much water and bleach should you use? answer: 3.2 cups of water and 0.8 cups of bleach. a) a mistake was made by reversing the ratio b) a mistake was made by using 4 as the total number of cups c) a mistake was made by using 5 as the total number of cups d) the given answer is correct

Explanation:

Step1: Define ratio parts

Water : Bleach = $4:1$, total parts = $4+1=5$

Step2: Calculate total solution volume

Total volume = $3.2 + 0.8 = 4$ cups

Step3: Verify ratio for given answer

Water share: $\frac{4}{5} \times 4 = 3.2$ cups
Bleach share: $\frac{1}{5} \times 4 = 0.8$ cups

Step4: Match to given answer

The calculated values match the provided answer.

Answer:

D) The given answer is correct
