Answer:
2/5
Step-by-step explanation:
To get the ratio as a pure number, it must be expressed as the quotient of two values that have the same units. For the purpose here, it is convenient to convert both values to units of seconds.
__
<h3>units conversion</h3>
The conversion factor between minutes and seconds is ...
1 minute = 60 seconds
Multiplying this equation by 3 gives ...
3 minutes = 180 seconds
__
<h3>ratio of interest</h3>
Then the desired ratio is ...
(72 seconds)/(3 minutes) = (72 seconds)/(180 seconds) = 72/180
= (36×2)/(36×5)
= 2/5
The ratio in its simplest form is 2/5.
1. x - y
2. xy
3. y / x
4. x+y
5. y= x-6
6. 6x =y
7. y-x
8. x/y
9. x+y= 6
10. xy= 6
The total percent discount on the jeans is 35% amounting to $77
<h3>Discount</h3>
- Cost of a pair of jean = $220
- Discount from last season = 15%
- Discount from Thanksgiving day = 20%
Total percentage discount = 15% + 20%
= 35%
Amount of discount = Total percentage discount × Cost of a pair of jean
= 35% × $220
= 0.35 × 220
= $77
Therefore, the total percent discount on the jeans is 35% amounting to $77
