$2 \frac{1}{2} \text{ metres "= 250" centimetres}$

#### Explanation:

Known:" "color(brown)( 1" metre "= 100" centimetres" )

But we need $2 \frac{1}{2}$ metres

Multiply both sides by $2 \frac{1}{2}$

$\textcolor{b r o w n}{\textcolor{b l u e}{2 \frac{1}{2} \times} 1 \text{ metre "= color(blue)(2 1/2xx)100" centimetres}}$

$2 \frac{1}{2} \text{ metres "= 250" centimetres}$

$2.5 \times 100 = 250 c m$

#### Explanation:

The prefix 'cent' means 100. [Century is 100 years, 100c = $1] In $1 \text{ metre }$there are $100 \text{ centimetres}$To change metres $\rightarrow$cm, multiply by 100. (move the decimal point 2 places to the right) If you change to a smaller unit, the number gets bigger. $2 \frac{1}{2} m = 2.5 m \text{ } \leftarrow$write as a decimal $2.5 \times 100 = 250 c m\$
