Question

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

Answer 1

The scientist only used 1/4 of solution he owned. That means he only used 1/4 of 3/4 liter of the solution.

solution used = 1/4 × 3/4
solution used = 3/16
solution used = 0.1875

He only used 3/16 L or 0.1875 L

Answer 2

Solution used for the experiment was 3/16 liter or 0.1875 liter

Explanation:

A scientist had 3/4 liter of solution {or 0.75 liter of solution }

Now, 1/4 of the solution used in an experiment.

i.e 1/4 of 3/4 liter

or (1/4) * (3/4) liter

or 3/16 liter

So we get:

The solution used by scientist in an experiment was 3/16 liter (or 0.1875 liter)
