The scientist had used 13/30 of the solution because you change 3/5 to 18/30, then 1/6 to 5/30. 18-5 is equal to 13 which gives me the answer to 13/30.
Answer:
1/10 liters.
Step-by-step explanation:
If the scientist had 3/5 Liter of solution and used 1/6 of it, he used (1/6)*(3/5) liters. In order to multilply fractions you have to multiply nominator with nominator and denominator with denominator as follow
[tex] \frac{1}{6} \times \frac{3}{5} = \frac{1 \times 3}{6 \times 5} = \frac{3}{30}[/tex]
Note that you can simplify this results dividing by 3 both nominator and denominator
[tex] \frac{3/3}{30/3} = \frac{1}{10}[/tex]
In conclusion, the scientist used 1/10 liters.
