Question

Maria is filling her 28liter tank with glasses that hold 1.75 liters each how many glasses will she gave to pour in to totally fill the tank if she uses full glasses

Answer 1

Solution:

Given that Maria is filling a 28 liters tank with glasses that hold 1.75 liters each, let the number of glasses she will have to pour inside the tank to fully fill the tank be represented as x.

This implies that

$\begin{gathered} \frac{1.75liters}{1\text{ glass}}\times xglasses\text{ =28 liters} \\ \text{Making x the subject of the formula,} \\ x=\frac{28liters}{1.75\text{ liters}}\times1\text{ glass} \\ \Rightarrow x=16\text{ glasses} \end{gathered}$

Hence, Maria will have to pour 16 glasses to totally fill the tank.
