2/5 of 1L = 400ML
500ml/1000ml(1l)=1/5
2/5
To express 400ml as a fraction of 1 liter, you can write it as \frac{400}{1000} 1000 400 since there are 1000 milliliters in a liter. Simplifying the fraction gives \frac{2}{5} 5 2 . Therefore, 400ml is equivalent to \frac{2}{5} 5 2 of 1 liter.
A half (1/2)
It is 3/20.
The working volume in a 500ml shake flask is typically around 20-25% less than the total flask volume, so it would be around 375-400ml. This allows for proper aeration and mixing of the culture without overflowing during shaking.
In it's simplest form, 2/5. or instead, 4/10, 8/20 and so on.
1/4....a litter =1000 ml
500 ml is 1/2 of a liter
1000 millilitres = 1 litre so 400 ml = 0.4 L. Simple!
