Here is an example:
Josh bought 7 apples for $21.
21/7 is 3, so one apple costs $3. This is the unit rate.
21/7 simplifies to 3/1, that’s another way to think about it. Simplify the fraction until the denominator is 1.
Hope this helps! Tell me if you have any questions!

Answer:
33 1/3%
Step-by-step explanation:
When you buy 20 ads, the per-ad rate is
$1200/20 = $60 . . . per ad
When you buy 80 ads, the per-ad rate is
$3200/80 = $40 . . . per ad
The percentage change to the $60 price is ...
((new price) - (original price))/(original price) × 100%
= ($40 -$60)/$60 × 100% = -20/60 × 100%
= -1/3 × 100% = -33 1/3%
The higher volume purchase comes with a 33 1/3% discount.
Answer
1 hour=60 minutes
Fraction= 35/60= 7/12
So your answer would be 7/12 :)
