Question

If $1 in U.S. Dollars is 0.1277 Chinese yuan, convert $16,000 to yuan.

Answer 1

To solve the exercise you can use a rule of three, like this:

`\begin{gathered} \text{ \$1 USD}\rightarrow0.1277\text{ Chinese yuan} \\ \text{ \$16,000 USD}\rightarrow x\text{ Chinese yuan} \end{gathered}`
`\begin{gathered} x=\frac{\text{\$16,000 USD }\cdot\text{ }0.1277\text{ Chinese yuan}}{\text{ \$1 USD}} \\ x=\frac{\text{16,000 }\cdot\text{ }0.1277\text{ Chinese yuan}}{\text{ 1}} \\ x=\frac{\text{16,000 }\cdot\text{ }0.1277}{\text{ 1}}\text{ Chinese yuan} \\ x=\frac{\text{2}043.2}{\text{ 1}}\text{ Chinese yuan} \\ x=2043.2\text{ Chinese yuan} \end{gathered}`

Therefore, $16,000 U.S. Dollars are 2043.2 Chinese yuan.
