Hi there!
I'm just gonna answer this and explain as I'm doing it.
So we have (3x10)x8= __x(10x8)
Well, first we look at what they did. They couldn't have changed the equation, but just moved things around.
Now, assuming you know your properties, I'm gonna go ahead and answer it.
(3x10)x8=3x(10x8)
^^
I used the Associative property, which basically says that when 3 or more #s are multiplied, the answer doesn't change no matter how you group the numbers. See how they just moved the numbers around, and only swapped the 3 for the 8?
Hope this helped!
Answer:
The boat travels (300.4 km / 11 hours) which is 27.30909091 kilometers per hour, So it would take 240 / 27.30909091 hours or 8.78828229 hours. (Which rounds off to 8.79 hours)

Answer:
0.55
Step-by-step explanation:
To write 0.11/0.2 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 0.11 by 0.2 what we write down as 0.11/0.2 and we get 0.55 And finally we have, 0.11/0.2 as a decimal equals 0.55
Original number is 20, so 4/5= 16
