For 175 : 250 divide them both by 25 to get 
< 
25 goes into 175 > 7 times > 25 into 250 is 10 times! >
For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us
.
8 goes into 16, 2 times and 40, 5 times.

Answer: Simple interest rate = 3%.
Step-by-step explanation: We are given invested amount = $5000.
Number of years of investment = 4 years.
Interest earned = $600.
Simple interest formula.
I = P R T.
Where I is the earned interest, P is the invested amount , R is the rate of interest and T is the time in years.
Plugging values in formula, we get
600 = 5000 × R × 4
600 = 20000R.
Dividing both sides by 20000, we get
0.03 = R.
Multiplying by 100 to convert it in percentage, we get
0.03 × 100 = R
R = 3 %.
