Hello :
<span>(25 + ki)(3+2i) = 75+50i +3ki -2k = (75-2k) +i (3k+50)
</span><span>the product (25 + ki)(3+2i) equal a real number: 3k +50 = 0
</span>k = -50/3
Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
