A solution is made from 3 mL of dextrose in 40 mL total. What percentage dextrose is this solution?

The percentage of dextrose is this solution  = 7.5 %

Step-by-step explanation:

A solution is made from 3 mL of dextrose in 40 mL total.

We can determine the percentage by dividing 3 mL by 40 mL and multiply the result by 100.

i.e.

3/40 × 100 = 0.075 × 100

                  = 7.5 %

Thus, the percentage of dextrose is this solution  = 7.5 %
