You have to have a number that ends with three zeros. You have to look at the number formed by the last three digits. If this number smaller or equal to 500, you round down, meaning you just replace the three digits by three zeros, if it is bigger than 500, you round up, meaning you replace the three digits by three zeros and add one to the digit of the thousands.
Here, the last three digits form the number 470 which is smaller than 500 so the nearest thousand of 65470 is 65000.
The ratio of men to women in a certain factory = 3:4
The total number of men in the factory = 222
Let us assume the common ratio to be = x
Then
3x = 222
x = 222/3
= 74
Then
The total number of women workers in the factory = 4 * 74
= 296
So
The total number of workers in the factory = 296 + 222
= 518
From the above deduction we can easily conclude that there are a total of 518 workers in the factory.
<span>Polly uses a probability simulator to pull colored ribbons from a bag 60 times and to flip a coin 60 times. The results are shown in the tables below:

<span><span>HeadsTails</span><span>3822</span></span>
<span>Using Polly's simulation, what is the probability of pulling an orange ribbon and the coin landing on tails?</span>
