Verified Answer :
The amount of blue paint in each container is \(\fbox{\begin\\\ 0.744 liters \end{minispace}}\).
Further explanation:
The mixture mixed by Mrs. Cleaver contains 1.24 litres of red paint with 3 times blue paint to obtain purple paint.
So, the amount of blue paint is calculated as,
\({3} \times {1.24}=3.72 \text { liters}\)
Therefore, the total amount of paint mixture is the sum of blue paint and red paint.
\(\fbox{\begin \\\begin{aligned} \text{Total paint}= 1.24+3.72\\=4.96 \text{ liters}\\\end{aligned}\\\end{minispace}}\)
Now, as Mrs. Cleaver divides the paint mixture equally in 5 containers so the amount of paint in one container is calculated as,
\(\boxed{\begin{aligned}\text{Amount of paint in one container}&= \dfrac{4.96}{5}\\ &=0.992 \text{ liters} \end {aligned}}\)
Since amount of blue paint mixed is three times the red paint so the fraction of blue paint to the total paint is \(\dfrac{3}{4}\).
Now, as it is known that the fraction of blue paint to the total paint is \(\dfrac{3}{4}\) and the amount of paint in a container is \(0.992 \text{ liters}\) then the blue paint in one container is calculated as,
\(\boxed{\begin{aligned}\text{Blue paint in one container} =\dfrac{3}{4} \times 0.992\\=0.248 \text{ liters}\end{aligned}}\)
Thus, the amount of blue paint in each of the five containers is \(\fbox{\begin\\\ 0.744 liters \end{minispace}}\).
