Answer:
7/11 (Simplified Already)
Step-by-step explanation: 25÷2235=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
25×3522=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2×355×22=70110
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 70 and 110 using
GCF(70,110) = 10
70÷10110÷10=711
Therefore:
25÷2235=711
Solution by Formulas
Apply the fractions formula for division, to
25÷2235
and solve
2×355×22
=70110
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,110) = 10
70÷10110÷10=711
Therefore:
2/5÷22/35=7/11
Answer:
The probability that an applicant does not get a job if he or she has an interview is 20%.
Step-by-step explanation:
- If the applicant has been interviewed, then she/he belongs to the group of 20 people that had an interview.
- 16 of the 20 people who were interviewed were offered a job, which means that 4 of the 20 people interviewed were not offered a job.
- Then, 4/20= 20% of the people who were intervied did not get a job, which means that the <u>probability that an applicant does not get a job if he/she were interviewed is 20%</u>.
- Pat attention: this probability results from analysing the probability of getting a job once you have had an interview (this condition restricts our attention to the group of 20 people who had an interview, and not to the hole group of 500 people who did apply for the job).
Step 1. Simplify
![\frac{1}{5} (x+5)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%28x%2B5%29)
to
![\frac{x+5}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B5%7D%7B5%7D%20)
Step 2. Simplify
![\frac{x+5}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B5%7D%7B5%7D%20)
to
![1+ \frac{x}{5}](https://tex.z-dn.net/?f=1%2B%20%5Cfrac%7Bx%7D%7B5%7D%20)
Step 3. Simplify
![\frac{1}{4} (x-3)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%28x-3%29)
to
![\frac{x-3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx-3%7D%7B4%7D%20)
Step 4. Cancel
![1](https://tex.z-dn.net/?f=1)
on both sides
Step 5. Multiply both sides by
![20](https://tex.z-dn.net/?f=20)
(the LCM of
![5,4](https://tex.z-dn.net/?f=5%2C4)
)
Step 6. Expand
Step 7. Subtract
![5x](https://tex.z-dn.net/?f=5x)
from both sides
Step 8. Simplify
![4x-5x](https://tex.z-dn.net/?f=4x-5x)
to
![-x](https://tex.z-dn.net/?f=-x)
Step 9. Multiply both sides by
![-1](https://tex.z-dn.net/?f=-1)
![x=15](https://tex.z-dn.net/?f=x%3D15)
Done! :) Hope this helps! :)
Yes 8.54 as rational number because in can be written as 854/100
So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}
