Okay, so we have a survey conducted where a thousand adults were asked to identify what is inappropriate in the workplace.
00:08
Of the 1 ,000 subjects, 70 % said that miniskirts were not appropriate in the workplace.
00:14
For part a, we want to find 70 % of 1 ,000.
00:18
So, 70%, we need to convert this firstly into a decimal.
00:23
So 70 % as a decimal, we need to divide by 100.
00:27
So remember, to convert from decimals to percentages, we need to either times or divide by 100.
00:35
So to go from percentage to decimal, we divide by 100.
00:38
So 70 over 100 is 0 .7.
00:42
So the decimal.
00:43
So now all we need to do is do 1 ,000 times 0 .7.
00:49
And this is going to be 700.
00:54
Okay, so 70 % of 1 ,000 is 700.
00:58
You can do this in different ways.
01:00
You could say what is 10 % of 1 ,000, and that's 100, and then times this by 7, and then you would get 700, and so on...
