#10%" decrease"#

5m to 4.5m is a 0.5m decrease.

To calculate as a percentage decrease express the decrease (0.5) as a fraction of the original amount (5) and multiply by 100.

#rArr0.5/5xx100/1=0.5/(cancel(5)^1)xxcancel(100)^20=0.5xx20=10#

undefined To find the percent of increase or decrease between two values, you can use the following formula:

$$ \% \text{ change} = \frac{\text{new value} - \text{old value}}{\text{old value}} \times 100\% $$

Where:
- "New value" is the value after the change.
- "Old value" is the initial value.

In this case, the old value is 5m and the new value is 4.5m.

1. Calculate the difference between the new value and the old value: $ 4.5m - 5m = -0.5m $
2. Plug the values into the formula:
$$ \% \text{ change} = \frac{-0.5m}{5m} \times 100\% $$

3. Calculate the percentage change:
$$ \% \text{ change} = \frac{-0.5}{5} \times 100\% = -10\% $$

Therefore, there is a 10% decrease from 5m to 4.5m.
