You can solve this by setting up a proportion. 4/6 = x/9. Cross multiply to get 6x=36. Divide both sides by 6 to get x=6.
Answer:
98.99%
Step-by-step explanation:
The combined reliability of both components must be 98%. Given that both components must be functional and have the same reliability 'r', the minimum value of 'r' that meets the system requirements is given by:

The level of reliability required for each component is 98.99%.
The lowest term is
.
Solution:
Given expression is 
<u>To reduce this term to the lowest term:</u>

Multiply the numerator and denominator.

Now, divide the numerator and denominator by the greatest common factor.
Here 150 and 8 both have common factor 2.
So, divide numerator and denominator by 2.



Hence the lowest term is
.
