How to convert Year to Decade

$$\text{Time}_{\text{dec}} = \frac{\text{Time}_{\text{yr}}}{10}$$

Examples

Example 1

Convert $35.0\ \text{yr}$ to $\text{dec}$.

$$\text{Time}_{\text{dec}} = \frac{35.0}{10}$$

$$\text{Time}_{\text{dec}} = 3.5$$

$$\therefore \ 35.0\ \text{yr} = 3.5 \ \text{dec}$$

Example 2

Convert $70.0\ \text{yr}$ to $\text{dec}$.

$$\text{Time}_{\text{dec}} = \frac{70.0}{10}$$

$$\text{Time}_{\text{dec}} = 7$$

$$\therefore \ 70.0\ \text{yr} = 7 \ \text{dec}$$

Example 3

Convert $110.0\ \text{yr}$ to $\text{dec}$.

$$\text{Time}_{\text{dec}} = \frac{110.0}{10}$$

$$\text{Time}_{\text{dec}} = 11$$

$$\therefore \ 110.0\ \text{yr} = 11 \ \text{dec}$$

Example 4

Convert $130.0\ \text{yr}$ to $\text{dec}$.

$$\text{Time}_{\text{dec}} = \frac{130.0}{10}$$

$$\text{Time}_{\text{dec}} = 13$$

$$\therefore \ 130.0\ \text{yr} = 13 \ \text{dec}$$

Example 5

Convert $185.0\ \text{yr}$ to $\text{dec}$.

$$\text{Time}_{\text{dec}} = \frac{185.0}{10}$$

$$\text{Time}_{\text{dec}} = 18.5$$

$$\therefore \ 185.0\ \text{yr} = 18.5 \ \text{dec}$$
