Answer:

Step-by-step explanation:
- Let the denominator be x
- So, numerator = x - 2
- According to the given condition: when 1 is subtracted from numerator and denominator both, the resulting new rational number in its simplest form is

By 91 dollars
because 22.75 times 4 is 91
14 days
.25 x 4days = $1.00
0.30x 10 days = $3.00
$3 + $1 = $4
