## Test Tip

Note the way we use prepositions with numbers and dates:

2000   40%
2010   25%

In 2010 the number decreased to 25 per cent. (40 -> 25)
In 2010 the number decreased by 15 per cent. (40 β 15 = 25)
In 2010 the number decreased from 40 per cent. NOT

The number dropped to 25 per cent between 2000 and 2010. (40 -> 25)
