Answer:
c) The reduced form of the given fraction 
Step-by-step explanation:
Here, the given expression is "24 over 30".
The given expression is is equivalent to 
Now by Prime Factorization:
24 = 2 x 2 x 2 x 3
30 = 2 x 3 x 5
⇒ The common factors in 24 and 30 is 2 x 3 = 6
So, 
Hence the reduced form of the given fraction 
V=(4/3)pir^3
r=9
V=(4/3)pi9^3
V=12pi243
V=972pi
aprox pi=3.14
3052.08 mi^3
P = A/D, Where P = Monthly payments, A = Total amount owed = 15,000-1,500 = $13,500,

r = 5% = 0.05, nt = 12*3 = 36
Therefore,
D =

= 33.37
Then,
P = 13,500/44.37 = $404.61
The correct answer is c.
