Question

Josiah needs to fill his 40 liter fish tank with water. He has already put in 34 1/4 liters of water. How many MILLILITERS of water does he need to add?

Answer 1

First you need to know what $34 1/4$ is in a decimal. It will equal $34.25$.
Then you need to know how many liters equal a millimeter. $0.001$ liters equal a millimeter, or in other words $1,000$ millimeters equals a liter.
Next you multiply, which you should know if that is $1,000$ then you just fill the multiplication problem with $0$. As in this equation if you multiply $34$ to $1,000$, you'll get $34,000$. So if you do $34.24$... it will change into $34,250$. If it was in a cubic way it would be $34,250,000$. So the answer is $34,250$, or $34,250,000$. But we're not finished until were done subtracting to get out answer.
$40$ liters equals $40,000$ millimeters, $40,000$ - $34,250$... which is $5,750$.

Answer 2

5 3/4 is the answer, hope this helped
