Answer:

7.5 Hours (This is questioned weird though so it could be different)

Step-by-step explanation:

Just add 9 to 6 and you'll have 15 divided by two equals 7.5.

Or since it takes 6 hours for both, multiply by 2 equals 12

Convert 11.42424242 to a rational expression in the form a/b, where b=0
lutik1710 [3]
I think you mean b is not equal to 0.

We have that 11.424242... = 11 + 0.424242...
Now let x = 0.424242...
Then 100x = 42.424242...
Now 99x = 100x - x = 42 so 99x = 42 and therefore x = 42/99

Now we can simplify 42/99 to 14/33

Now combining this we get 11.424242... = 11 + 14/33
= 363/33 + 14/33 = 377/33
