A report on the number of police officers in 1995 said:

"There were 119 000 police officers. Almost 15% of them were women"
a) the percentage was rounded to the nearest whole number,15.
what is the smallest value the percentage could have been, to one decimal place. choose one out of the following:
14.1%,14.2%,14.3%14.4%,14.5%,14.6%,14.7%,14.8%,14.9%

b)what is the smallest number of women police officers that there might have been in 1995?(use your answer to part (a)to help you calculate your answer)

When do we round up?
 
i don't know, the question just said that the percentage was rounded to the nearest whole number, i don't understand it either
 
No, I was asking you a general question. Round the following numbers to 1 decimal place:
0.12, 0.15, 0.18.
 
Why would you think that 0.12 = 12/100 would be larger than 1.2 = 120/100 or 12 = 1200/100?

Eliz.
 
One decimal place:

0.12

Move to the right one decimal place, and place bar between the 1st and 2nd digit:

0.1|2

Look at the number to the right of the bar. If it less than 5 then the 1 stays. If it is 5 or greater than 5, round the digit 1 up.
 
oh yeh lol sorry! it's just that i haven't been doing no revision and i wasn't even thinking sorry. 0.15>15
 
I'm sure there's a perfectly legitimate reason behind your 0.15>15 statements.

So let us continue what we were doing.
 
Try rounding the numbers I gave.

The next step will be converting your percentages to decimals and rounding those.
 
so the closest decimal would be 14.9% in it? because when it is 149 in it? or am i just completely wrong?
 
Ok, now I becoming concerned.

Round 0.18 to one decimal place.

We want to be left with a number like 0._ <- one digit after the zero.
