Answer 2

Answer:

400 litres

Step-by-step explanation:

When it is three-quarters ($\frac{3}{4}$) full, a storage tank is holding 450 litres

∴ When it is full, it will contain $\frac{450}{\frac{3}{4} }$litres = 450 x $\frac{4}{3}$ litres = 600 litres

∴ When it is two-thirds ($\frac{2}{3}$), it will contain 600x$\frac{2}{3}$ litres = 400 litres
