Question

Selma will mix color. To get the right shade, she needs to take 1 cl dark green color to 1.5 dl white color. She has 1 dl dark green color. How many liters of finished paint is enough?

1,6 liter is the answer but how do I get it?

Answer 1

1(liter) = 100 cl

1(liter) = 10 dl

1 cl = 0.01 (liter)

1 dl = 0.1 (liter)

1 cl (dark green) → 1.5 dl (white) ← needed proportion for mix colors

1 dl (dark green) → x (white) ← needed proportion for available 1dl of dark green paint

Converting to liters and writing the proportion:

0.01/0.1 =0.15/x → solving for "x"

x = 1.5 (liters of white paint)

Amount of paint needed to mix colors for 0.1 liters of green color (in liters):

0.1 (liters) of dark green and 1.5 (liters) of white

Calculating the total:

1.5 + 0.1 = 1.6 (liters of paint)
