A paint color is made by using 4 drops of red and 5 drops of blue for each 5 gallons of paint . How many gallons of paint are being colored when 45 drops are used ????
Answers
Final answer:
With 4 drops of red and 5 drops of blue used for every 5 gallons of paint, this forms a 9:5 ratio.
With 45 drops, which is 5 times 9, the there would be enough color for 25 gallons of paint.
Explanation:
A ratio states the relative sizes of two or more values. In this case, it is said that for each 5 gallons of paint, there are 4 drops of red and 5 drops of blue, making a total of 9 drops of color for every 5 gallons of paint.
To figure out how many gallons of paint are being colored with 45 drops, you would find out how many 'sets' of 9 drops are in 45, which is 5.
So, there are enough drops to color 25 gallons of paint (5 sets times 5 gallons per set).

we have to be careful, and THINK .
I was going to ask you "What does Ф mean ?", and then I realized,
Ф is a new operation that the teacher invented.
The first line on the board is the definition of Ф .
Ф means "Add the two numbers and subtract 4."
Now you have to use this new invention to find the value
of the second line:
Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
Add the two numbers and subtract 4
4 + 2 - 4 = 2
That's the part inside the parentheses. It's 2 .
NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:
3 Ф 2
Add the two numbers and subtract 4
3 + 2 - 4 = 1
And that's the final value of 3 Ф (4 Ф 2) . It's 1 .
Pretty sneaky.
