Answer:
k=172.2
Step-by-step explanation
When you search up (0.6888) into a fraction calculator you get (861/1250),
which clearly needs to be simplified. Easy find the LCD. We already know that 1250 needs to be 25. So, divide (1250/25=50)
So know we know that the LCD is 50. Now we need to divide 861 by the LCD. (861/50=172.2)
k=172.2
