I'm not sure exactly what you're asking but 1×10^-5 is .00001. I could be interpreting your question wrong in which case I'm sorry.
Answer:
4 1/2 hours
Step-by-step explanation:
To find how long, multiply the length of time in hours by the number of cakes. 1 cake takes 3/4 of a an hour so 6 cakes will take
3/4 * 6 = 18/4 = 4 2/4
4 2/4 simplifies to 4 1/2 hours.
X + 1/4x + 1/5x = 58
20/20x + 5/20x + 4/20x = 58
29/20x = 58
x = 58 * 20/29
x = 1160/29 = 40 <== the original number
