In a laboratory, a technician combines a salt solution contained in 27 test tubes. Each test tube contains 0.06 liter of the solution. If he divides the total amount into test tubes that hold 0.3 liter each, how many test tubes will he need?

Respuesta :

Answer:

We need 6 test tubes

Step-by-step explanation:

We have given that there are 27 test tubes and each contain 0.06 liters of solution

So total amount of solution [tex]=27\times 0.06=1.62liters[/tex]

Now he divides the total amount into test tubes which contain 0.3 liters each

We have to find the total number of test tubes

So total number of test tubes [tex]=\frac{total\ amount}{amount\ contin\ by\ eac\ test\ tube}[/tex]

[tex]=\frac{1.62}{0.3}=5.4[/tex]

As test tubes can't be in fraction so we need 6 test tubes
