Five beakers contain an average of 15 mLs of a solution. A scientist finds a sixth beaker and wants to redistribute the solution equally among these six beakers. How much liquid will be in each beaker?

2.5 mL

Step-by-step explanation:

What we must do first is calculate the total amount.

We know that there are 5 beakers with 15 mL, therefore in total it is:

15 * 5 = 75 mL

Now we want to divide that by 6. So divide by 6.

75/6 = 12.5 mL

For the 6 beakers to have the same amount, they must have 12.5 mL each.

Now, I divide this value by the number of beakers that have 15 mL. that is 5.

12.5 / 5 = 2.5 mL

This means that from each beaker the 6th beaker must receive 2.5 mL, to have a total of 12.5 mL and thus all have the same amount.

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4
