If 40% of students prefer keyboarding, 40/100*40=16 students like it best. If the remaining students prefer English, then 40-16=24 students like English best. Since 24 is more than 16, most students prefer English.

QUESTION POSTED AT 14/12/2019 - 05:45 PM

It was estimated that the united states would need 6200 more veterinarians in 2012. The percent error was 10%. if the estimate was low,how many were actually needed

5580 veterinarians were actually needed. 

To find this you must find what is 10% of 6200. 

In math, of = multiplication

So you multiply 10% and 6200. In order to do so, you must turn the percentage into a decimal or fraction. So 0.1 x 6200

That should get you 620. However, that IS NOT your final answer, since 620 is only 10% of the total, not the amount needed.

To get the actual amount of veterinarians, you subtract 620 from 6200, and should get 5580, the final answer.

Whats the percent increase from 20 students to 30 students rounded to the nearest percent

Given Situation: What is the percent increase from the 20 students to the 30 students. Solution: => Let’s find how many percent did it increase. Let’s have 20 as the first total number of the students in the first counts. => Then it became 30 students, let’s find out how many students added. => 30 – 20 = 10, there are 10 students added 10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.

Each veterinarian has seen 40 animals today. Two out of every 5 animals Vet A has seen have been dogs. Three out of every 8 animals Vet B has seen have been dogs. Which vet saw more dogs today? Explain your reasoning.

Basically, the fractions are 2/5 vs. 3/8. As always, in order to compare fractions, you must first have a common denominator. The easiest way to achieve that is by multiplying the two denominators by each other. 5*8=40. You must also multiply the numerators by the same thing you multiplied the denominators by, so 3*5=15, and 2*8=16. The new fractions are 16/40 vs. 15/40. Therefore, Vet A has seen more dogs.

What percent is 33 of 96?


1. We assume, that the number 96 is 100% - because it's the output value of the task. 
2. We assume, that x is the value we are looking for. 
3. If 96 is 100%, so we can write it down as 96=100%. 
4. We know, that x is 33% of the output value, so we can write it down as x=33%. 
5. Now we have two simple equations:
1) 96=100%
2) x=33%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
96/x=100%/33%
