Answer:
100 revolitions
Step-by-step explanation:
180s = 3min
50s = 1min
50 * 2 = 100
you would need to make 0.03 a whole number 1st, so you take the decimal point and move it 2 places, and you do that to 8.4.
Now, divide the way you would usually do. If there is a remainder, keep adding 0's until you get the answer with no remainder. If the 0 keeps going on and on just stop after 2 0's.
The quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3
<h3 /><h3>How to solve fraction</h3><h3 />
n³ / (2n - 6) ÷ n³ / (3n - 9)
- multiply by the reciprocal of n³ / (3n - 9)
= n³ / (2n - 6) × 1 / n³ / (3n - 9)
= 2n - 6 / 3n - 9
= 2(n - 3) / 3(n - 3)
= 2/3
Therefore, quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3

First you would have to set it up so that the fractions line up: 7/8
<u>- 5/8
</u>Since the denominators (8) are the same, you can just subtract the numerators. You then get 2/8, which can be simplified. If you divide both the numerator and the denominator by two, then your final answer becomes 1/4.
I think the answer to that is 18.6
