    Hello,

    Ok, i'll try to explain^^

    A ratio 1:4 means that for x red paint, you will have 4x white paint.

    This means that for 1 liter of red paint, you will have 4 liters of white paint. The total is 5 liters.

    Now, you're looking for x such as x+4x make 40mL of pink paint.

    So 5x=40mL

    -> x=... ? quantity of red paint
    -> 4x=... ? quantity of white paint
