Step-by-step explanation:
Answer:
is smaller than
.
Step-by-step explanation:
- Find the least common denominator or LCM of the two denominators:LCM of 3 and 10 is 30
- For the 1st fraction, since 3 × 10 = 30,
![\frac{1}{3}=\frac{1x10}{3x10}=\frac{10}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%3D%5Cfrac%7B1x10%7D%7B3x10%7D%3D%5Cfrac%7B10%7D%7B30%7D)
- <em><u>Likewise, for the 2nd fraction, since 10 × 3 = 30,</u></em>
![\frac{4}{10}=\frac{4x3}{10x3}=\frac{12}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D%3D%5Cfrac%7B4x3%7D%7B10x3%7D%3D%5Cfrac%7B12%7D%7B30%7D)
- <u><em>Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction</em></u>

Answer:
The situation that represents this situation is:
![t = \frac{60}{n}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B60%7D%7Bn%7D)
Step-by-step explanation:
The amount of time t needed to assemble the set is inversely proportional to the number people n working.
This means that:
![t = \frac{k}{n}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bk%7D%7Bn%7D)
In which k is the constant of proportionality.
Twelve people can assemble the set in 5 hours.
This means that for
. We use this to find k.
![t = \frac{k}{n}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bk%7D%7Bn%7D)
![5 = \frac{k}{12}](https://tex.z-dn.net/?f=5%20%3D%20%5Cfrac%7Bk%7D%7B12%7D)
![k = 12*5 = 60](https://tex.z-dn.net/?f=k%20%3D%2012%2A5%20%3D%2060)
Write an equation to represent the situation.
![t = \frac{60}{n}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B60%7D%7Bn%7D)
Answer: $20
Step-by-step explanation:
Here os the correct question:
Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?
Let the original price of the perfume be y.
Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:
y - (25% of y) = $15
y - (25/100 × y) = $15
y - 0.25y = $15
0.75y = $15
Divide both side by 0.75
0.75y/0.75 = $15/0.75
y = $20
The original price of the perfume is $20
