There are 800 members in an astronomy club and 320 of the members are females. What percent of the members are males.
First, we need to understand what the question is asking us to do. We know that there are 800 members in the club and that 320 of the members are females. To find out how many males there are, we can subtract 320 from 800 and we will get us a difference of 480. We now know that 480 of the members in the astronomy club are males.
To find what percent are males, we can make a fraction. 
represents the 480 males out of the entire club.
We can turn into a fraction. We can reduce by dividing both the numerator and denominator by the greatest common factor of 480 and 800 using 160.
Finally, we have our reduced fraction which is 
3 ÷ 5 = 0.6
0.6 × 100 = 60%
Therefore, 60% of the members in the astronomy clubs are males.

Answer:
7,000 milliliters
Step-by-step explanation:
In this question, we are asked to calculate the amount in milliliters of soft drinks coach Jull put in each of the coolers.
From the question, we know that there are 28 coolers and she divided the drinks therein equally into 4 different coolers. The amount of drinks in one of the coolers would be 28/4 = 7L of drinks per cooler
Now to get our final answer, we will need to convert the liters to milliliters. That would be a multiplication with a factor of 1000 as 1000 milliliters make one liter.
Hence 7 liters would be 7 * 1000 = 7,000 milliliters
