Question

a scientist had 3/4 liter of solution. he used 1/6 of the solution for an experiment. how much solution did the scientist use for the experiment?

Answer 1

The answer is 7/12 because 3/4 - 1/6= 7/12
3/4 converts to 9/12 and 1/6 converts to 2/12. The domanaters stay the same, but 9-2=7. that is how you get 7/12

Answer 2

3/4 = 9/12
1/6 = 2/12
9/12 - 2/12 = 7/12
The answer is 7/12
