First you would convert it to a fraction. 9/100
Once you do that you divide the numerator, which is 9 by the denominator, which is 100.
Then we get our answer, 0.09
Answer:

Step-by-step explanation:
The answer would be
because
= 
9^3 x 8 is the answer I believe
Answer:
15 mL of the solution with 20% water will be needed.
Step-by-step explanation:
Use the inverse relationship
10 mL * (18-15)% = x mL * (20-18)%
x = 10 mL * (3/2) = 15 mL
18. equivalent
16x5 does equal 10x8
19. equivalent
13-0 does equal 0
20. Not equivalent
12-2 doesn’t not equal 7-3
For all three of these equations you have to use PEMDAS (systems of equations) so first you solve everything that’s in parentheses, then any exponents, followed by multiplication,division,addition, and lastly subtraction. You MUST follow that order to get the correct answer.
