Question

Mary mixes white paint to blue paint in the ratio 2:3
She makes a total of 20 litres of paint.
How much more blue paint does she need to add to the mixture so that the ratio of white paint to blue paint becomes 1:7?

Answer 1

Answer:

44 L

Step-by-step explanation:

2+3=5------2:3

20:5=4

white in 20 L--4*2=8 L

blue in 20 L----4*3=12 L

if 8 is 1

8*7(bc 8 is 1 and it should be 1:7)=56

if there is already 12 L of blue you need to add 56-12=44 L

hope this helps (:
