To solve, apply the formula:

| Approximate Value - Exact Value |

% error = --------------------------------------- `xx` 100

Exact Value

So, plug-in Approximate Value= 4.43 and Exact Value=4.07.

`% error= |4.43-4.07|/4.07*100`

`%error=0.36/4.07*100`

`% error =8.85%`

**Hence, the percent error is 8.85% .**

((4.43-4.07)/4.07)*100=8.85% error
