Answer to 9:

  1. Make your denominators the same. Since 9 goes into 54 6 times, multiply the numerator and denominator of -1/9 by 6. \frac{-6}{54} =\frac{-1}{9}
  2. Add numerators together. \frac{9}{54} +\frac{-6}{54} = \frac{3}{54}
  3. Reduce and your answer should be 1/18

Answer to 10:

  1. Find the LCM (least common multiple), which is 36.
  2. Multiply the numerator and denominator from 6/12 by 3 to get it to have a similar denominator as the second fraction.
  3. Multiply numerator and denominator from -4/9 by 4 to get to same denominator as the first fraction.
  4. Add the fractions together and reduce. \frac{18}{36}+\frac{-16}{36}=\frac{2}{36}=\frac{1}{18}
  5. Your answer should be 1/18.

9. 1/18

10. 1/18

<u>Here is how I got my answer for 9:</u>

Step 1: Simply 9/54 to 1/6. Which leaves us with 1/6 - 1/9

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator. By multiplying 6*3 and 9*2. Which leaves us with 3/18 - 2/18.

Step 4: Subtract 3 and two, giving you your answer: 1/18

<u>Here is how I got my answer for 10:</u>

Step 1: Simplify 6/12 to 1/2. Which leaves us with 1/2 - 4/9

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator by multiplying 2*9 and 9*2. Which leaves us with 9/18 - 8/18.

Step 4: Subtract 9 and 8, giving you your answer: 1/18

25% assuming you don’t count the car with 18 mpg fuel efficiency.

if you add the amount of cars up that have less than 18 mpg and then divide it by the total number (12) you will get a decimal (0.25) to find the percent multiply the decimal by 100
