Exponents and roots come first, then multiplication and division, and finally addition and subtraction.

Question: how many gallons of yellow paint, and how many gallons or red paint, to make two gallons of orange paint? However, in this section of the text book, I'm not sure that it's "allowed" to do any of that.
Visit Stack Exchange Four gallons of yellow paint plus two gallons of red paint make orange paint. Is it possible to solve this just with cross-multiplying a ratio?
When two ratios are equal in value, then they are said to be in proportion. The two terms ‘b’ and ‘c’ are called ‘means or mean term,’ whereas the terms ‘a’ and ‘d’ are known as ‘extremes or extreme terms.’ Let us consider one more example of a number of students in a classroom. Thus, multiplying the first ratio by c and second ratio by b, we have First ratio- ca:bc Second ratio- bc: bd Thus, the continued proportion can be written in the form of ca:bc:bd Ratio and Proportion Tricks With Example Questions Question 1: Are the ratios 4:5 and said to be in Proportion?
Our first ratio of the number of girls to boys is 3:5 and that of the other is 4:8, then the proportion can be written as 3 : 5 :: 4 : 8 or 3/5 = 4/8 Here 3 & 8 are the extremes, while 5 & 4 are the means. Then in order to find the continued proportion for the two given ratio terms, we convert the means to a single term/number. Solution: 4:5= 4/5 = 0.8 and 8: 10= 8/10= 0.8 Since both the ratios are equal, they are said to be in proportion.
In the following example, the question asks you to determine the total number of socks between the two sisters.
The unit of measurement for this problem is pairs of socks.
Using common sense, estimate an answer and see if you come close to what you expected.
If the answer seems absurdly large or too small, search through the problem to find where you went wrong.
Subtract the two missing pairs for a final equation of (8 6 9) - 2 = n, where n is the number of pairs of socks the sisters have left.
Using the equation, solve the problem by plugging in the values and solving for the unknown variable.
