Explanation

Since red paint makes up 3/4 of the mixture, we find 3/4 of 60 ml. The chapter earlier established that 3/4 = 75%, so this is equivalent to finding 75% of 60 ml.

Solution Steps

  1. Identify the total amount of paint (60 ml) and the fraction representing red paint (3/4).

  2. Multiply the total amount by the fraction: (3/4) × 60 ml.

  3. Calculate the result: 45 ml.

  4. Alternatively, convert the fraction to a percentage: 3/4 = 75%.

  5. Calculate using the decimal equivalent: 0.75×600.75 \times 60 = 45 ml.
