Answer:
A = P(1+r÷100)^n
where A is amount after some days
r is the rate
n is the number of years
p is the principle (the amount of money before the interest)
A = 5000 ( 1 + 12÷100)^5
A = 8811.70
A = 8812
No I do not think that 12/60 and 16/40 are equivalent because onec you reduce both of the fractions it does not equal.
