Answer:
A. Every minute, 2/3 of a gallon is drained, so the rate of change would be -2/3
B. It would take 7.5 minutes to drain the tank
"9 and 9?" Did you possibly mean {2, 5, 6, 9}?
The least common multiple of a set of numbers is the smallest integer that can be divided evenly by all of the numbers. In this case, when I saw the 9 and 5, I thought, "45!" but 45 is not evenly divisible by 2 or 6.
So, I tried 90. 90 is indeed divisible by {2, 5, 6, 9}, and is thus the LCM.
Look up and review "Least common multiple."
Ok, so first convert both the numbers to improper fractions. (Multiply the denominator of the fraction by the whole number and add the numerator of the fraction)
Then keep the first number the same, change the division symbol to a multiplication symbol and use the reciprocal of the second number. (flip the numbers so that the denominator becomes the numerator and the numerator becomes the denominator.)
Then simply multiply across.
First you would add 5/6 and 3/6 which would be 8/6. Next you would convert the improper fraction (8/6) into a mixed number which would be 1 2/6. Now just add 7 and 2 which is 9. Finally you would add the whole number and the mixed number. So your answer is 10 2/6 unless the instructions say to simplify then your answer would be 10 1/3.
