Few programmes can boast that 100 percent increase in their viewing audience since first going on air, but March of the Day which celebrates its 30th birthday this week proudly makes that claim. The first programme attracted just 50,000 viewers. Tonight it is estimated that the audience will be in excess  of five million.

Re: need help

thanks
so 100 percent of 50 000 would be 50 000. THerefore it has to be 100 time 50 000 rather than 100 percent of 50 000.
Is that right?
thanks for your help so far
its sooooo helpful!

Re: need help

You can also say that the percentage increase is not 100% but 9900%. big_smile

No. The error is that it is 100 times more or 9900% more rather than 100% more. smile

Re: need help

Technically no error was made there. The viewing figures did indeed increase by 100%, its just that they also increased by considerably more than that.

The only possible error there is that other programmes that managed to increase their viewing figures by that much were said to have not, but as we aren't told about any other programmes then we don't know that that's true.


Why did the vector cross the road?
It wanted to be normal.
