A factory was painted with 140 litres of pink paint. The pink paint was made by mixing red and white paint together. It took 30 litres of red paint to make the mix. Express in the lowest terms the ratio of red and white paint used.

is there any photos or whatever?

answer: idk

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
