Part 1: <span>What is the periodic interest rate of jade investment?
Each compounding period is done semi-annually, which means twice a year. Since the given interest rate is annual, then 5.2% divided by half should yield the period interest rate, which is 2.6%
Part 2: </span><span>How many compounding periods does Jade's investment offer in a year? how about in 8 years?
In 1 year, there are 2 compounding periods. In 2 years, there are 16 compounding periods.</span>
No because irrational cant be a simple fraction and 9/15
is 0.6
so... it is not irrational
Let the total no. of 25 p coins be x
50p coins = 2x
Value of 25 p coins ( in rupees) = 0.25*x =0.25x
Value of 50p coins ( in rupees) = 0.5*2x = x
0.25x+x = 25
1.25x =25
x = 25/1.25 = 20
no. if 25p coins = 20
and 50p coins = 2*20 = 40
