Answer: i believe it is B
Step-by-step explanation:
Total portions are
5+4+3
12
One portion,
4860 / 12
405
So
5 : 4 : 3
5*405 : 4*405 : 3:405
2025 : 1620 : 1215
Using proportions, it is found that Mrs. Wood should expect 1,898 books out of the 36,500 to have major damage.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For this problem, the proportion of books with major damage is:
43/(716 + 68 + 43) = 0.051995.
Hence, out of 36,500 books, the expected amount of books with major damage is:
0.051995 x 36,500 = 1898.

Answer:
PEMDAS
Step-by-step explanation:
Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3
Then, go to your exponents. Since we don't have any, we skip this step.
Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.
Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.
The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.
2+5=7.
