If 25 students took an exam and 4 of them failed, what percent of them passed?
lisabon 2012 [21]

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?

To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.

The fraction \frac{21}{25} represents the number of students who passed the exam out of all the students.

To find out what percent of the students passed, we can turn \frac{21}{25} into a percent.

21 ÷ 25 = 0.84

0.84 × 100 = 84%

Therefore, 84% of the students who took the exam passed.

Anna11 [10]

Answer:

\large\boxed{4.7\times(6.02\times10^{23})=2.8294\times10^{24}}

Step-by-step explanation:

The scientific notation:

a\times10^k\ \text{where}\ 1\leq a

We have:

4.7\times(6.02\times10^{23})=(4.7\times6.02)\times10^{23}=28.294\times10^{23}\\\\=2.8294\times10\times10^{23}=2.8294\times10^{24}
