Question

3.7 is 2.5% of what number ? 3.7 is 2.5% of …?

Answer 1

To find the number we use a rule of three:

$\begin{gathered} 3.7\rightarrow2.5 \\ x\rightarrow100 \end{gathered}$

Then:

$\begin{gathered} x=\frac{100\cdot3.7}{2.5} \\ x=148 \end{gathered}$

Therefore the number we are looking for is 148.
