There are 18 green blocks in a bag. THere are 3 white blocks for every 2 green blocks. Which proportion can be used to find w the total number of white blocks in the bag
A.18/w=3/2
B.3/8=2/w
C.18/w=2/3
D.2/3=w/18

Tracy rakes leaves to help her parents she can rake 4 bags of leaves in 40 minutes at this rate how many bags can she rake in 2 hours?
12
There cannot be 3 white for every 2 green in 18 blocks. For every 5 blocks, 3 will be white and 2 will be green. 18 is not a multiple of 5.
If Jeremy drinks 2 pints in 3 days, 60 days is 20 times 3 days. Therefore 2 * 20 = ?
1st one:
18 green for x whites
2 green for 3 white
so 3/2 = w/18 OR 2/3 = 18/w which is A
2nd:
3 days ---> 2 pints
60 days ---> x pints
x/2 = 60/3
x = 2(60/3) = 40 , which is D
3rd:
4 bags in 40 minutes
x bags in 2 hours or 120 minutes
x/4 = 120/40
x = 4(120/40) = 12 bags , you are correct
The " 3 white blocks for every 2 green blocks " is just a ratio
3 : 2 or
= 6:4 or
= ... or
= 27 white : 18 green

To find the total number of white blocks in the bag, you need to use a proportion.
Let's denote the total number of white blocks as "w". According to the information given, there are 3 white blocks for every 2 green blocks.
So, the proportion to find "w" would be:
Green blocks / White blocks = 2 / 3
Since the question asks for the proportion, we can re-arrange the equation:
Number of green blocks / Number of white blocks = 2 / 3
Therefore, the correct proportion to find the total number of white blocks in the bag is:
C. 18 / w = 2 / 3
