Question

what number is 15% of 45.4

Answer 1

Let the number be y.

If 15% of 45.4 is y, this implies that

$\begin{gathered} \frac{15}{100}\times45.4=y \\ \\ \end{gathered}$

Thus, we have

$\begin{gathered} \frac{15\times45.4}{100}=y \\ \Rightarrow\frac{681}{100}=y \end{gathered}$

Evaluating y,

$\begin{gathered} y=\frac{681}{100} \\ \Rightarrow y=6.81 \end{gathered}$

Hence, the number is 6.81.
