Regarding your (1/10 divided by 2/5): I'm going to regard this as
(1/10) divided by (2/5).
First, write
1
---
10
Invert the fraction 2/5 and then multiply 1/10 by 5/2:
1(5)
-------- = 1/4, after reducing 5/10.
10(2)
Thus, <span>−34+(1/10÷2/5) yields -34 + 1/4, or -33 3/4.</span>
<span>MP3 player is $60
</span><span>The selling price is $105
</span><span>A classmate says that the markup is 175% because $105/$60=1.75 . Is your classmate correct?
No. IT's not correct
Original price $60
Selling price $105
$105 - $60 = $45
So
45/60 x 100 = 75%
Price is markup 75% from $60 to $105</span>
