Maths quiz

Spot the fallacious maths in this story from the BBC website.

Hint: it is in this paragraph:

So what’s causing such a change in behaviour – with hit and runs doubling in less than a decade? In London in the 1990s, hit and runs were 8% of accidents, now they’re 16% – with 25% in the borough of Hackney.

    Ummm. The lazy assumption that the overall level of accidents is constant? If (for example), the number of accidents had halved over that period, then there would be no increase in the number of hit-and-runs.

    You are a walking advert for the qualities of Ifield school.

    Damn Right. Got to give ‘props’ to Mrs Webb.
