Answer:
8 divided by 1/3 is 24 because you are dividing a fraction so it is basically 8*3 (inverse operations). As for 2/3 it does not have one as a numerator so it automatically is less that 1/3
Step-by-step explanation:
Sry If it doesn't make sense!
If you are confused let me know and I will explain in the comments.
Step 1
Given;

Required; To find the difference in interest between the two periods.
Step 2
State the formula for simple interest

Step 3
Find the interest when the rate is 8%

Therefore the interest is given as;

Step 4
Find the interest in 1980 with a 20% rate

The interest is given as;

Step 5
Find the difference in interest between the two rates.

Hence, the difference in interest between the two rates = $11095.89
Since, the system of linear equations are parallel
so, they will never cross or intersect each other
And we know that
solution can only be found if both lines intersect atleast one point
But here , lines are parallel
so, they never intersect each other throughout number line
Since, they never intersect
so, we won't get any common value between both lines
Hence,
There is no solution...........Answer
