Hello the 3rd one is your answer. Do you have to show work?
8/9 - 1/3
To subtract these two fractions, first find a common denominator.
The common denominator will be the
least common multiple for the two denominators.
In this case, the least common multiple of 9 and 3 is 9.
So to subtract, a denominator of 9 is needed in each fraction.
8/9 already has 9 in the denominator so it stays the same.
To get a 9 in the denominator of 1/3, multiply top and bottom by 3.
This gives us 3/9.
So we have 8/9 - 3/9 which is 5/9.
For this case the density is given by:
D = fish / volume
By clearing the volume we have:
volume = fish / D
Substituting values:
volume = (8) / (0.2)
volume = 40 feet ^ 3
Answer:
the volume of the tank is:
40 ft3
