You started out with 260, and increased to 430.
The amount you increased was (430 - 260) = 170
170 is (170/260) = <em>65.4%</em> of what you started with.
============================
Another way:
The new amount is (430/260) of the old amount.
430 / 260 = 1.654 = 165.4%
The original amount was 260.
You started with 100% of it.
You ended up with 165.4% of it.
That's an increase of 65.4% .
Answer: half year
Step-by-step explanation:
The formula to find the simple interest is given by :-
, , where P is the principal amount , r is the rate of interest and t is the time in year.
Given : I=420 ; r=14%=0.14 and P =$6000
Then, we have the following equation :-

It means the duration of the loan is half year .
3/4 2/3
This is a multiplication of fractions
1.- Multiply the numerators and the denominators
3/4 x 2/3 = (3x 2) / (4 x 3)
= 6/12
2.- Simplify
= 3/6
= 1/2
