The answer to the selceted problem 23/50
A rational number is a number that can be written in the form:
Where p and q are coprimes. We are asked for finite sets, we can rule out options 3 and 4. In the set in option 2 the first element is:
This number cannot be written a ratio. We can rule out option 2.
All the elements in the set from option 1 can be written in the form p/q.Thus, the answer is the first option.

IF MARTHA EARNS 3.25/HOUR FRO BABYSITTING (SHE IS UNDERPAID!)
IN 1.5 HOURS=3.25*1.5=4.88 DOLLARS
IN 2.5 HOURS=3.25*2.5=8.13 DOLLARS
IN 3.5 HOURS=3.25*3.5=11.38 DOLLARS
To solve this problem, you should find the rate ---> cost per yogurt (cost/yogurt)
$6.50/10 yogurts = $0.65/yogurt
It costs $0.65 per yogurt, so you can multiply 9 by $0.65 to find the total cost of 9 yogurt.
9(0.65) = $5.85
