7+ . My first attempt three years ago was 6 in writing. I was bitterly disappointed.
And what was your most recent score?
From 2006 to 2008, the percentage of computer ownership increased 5% to reach 80%
Which preposition fits in the sentence, "increase by", "increase at" or "increase to"?
by
There's an important difference between
percentage increase and
increase by percentage points. For example, let's say the unemployment rate starts the year at 8% and finishes the year at 12%. That's an increase of
50%, not 4%. You can, however, say that there was an increase of 4 percentage points.
Is the following sentence correct now?
The computer ownership witnessed modest increase (by) (at) (to) about 5% in 2008 in the UK.
1) There's no reason for
The.
2) You've missed an indefinite article
3) The preposition should be
of.
4) I don't like your use of
witnessed. I think it's wrong.
5) The maths is wrong. You're talking about percentage points, not percentages.
I used "about" because I am not sure it is 5% It is not clear in the chart.
That's okay, but I'd suggest you use 'approximately' instead, which is more academic.
Is the computer ownership singular because computer acts as an adjective describing ownership?
Yes.
I usually use "witnessed" instead of "saw".
You can use either one, but you should learn how to use them properly. In your example sentence, I consider them wrong, as would many others.
