Question

Express $7l50ml$ in litres $\left(l\right)$ using decimals.

Answer 1

We know that, $1l=1000ml$

Since, we are converting the lower unit to the higher unit. So, we will divide the smaller unit to get the bigger unit.

$$\begin{gathered} 7l50ml=7l+50ml \\ 7l50ml=7l+\frac{50}{1000}l \\ 7l50ml=7l+0.050l \\ 7l50ml=7.050l \end{gathered}$$

Hence, $7l50ml=7.050l$
