Answer:

Multiplying a complex number by a real number

Explanation:

For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0. Similarly, when you multiply a complex number z by 1/2, the result will be half way between 0 and z.

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
