If Reginald answered 78% correctly out of a total 100%, we can subtract 78 from 100:

100 - 78 = 22

He answered 22% of the question incorrectly. But how do we find the bottom number? Remember what we said earlier. The <u>total</u> is 100%. He got 22% out of 100% wrong. Wouldn't that be \frac{22}{100}?

Now that we know our fraction, we can reduce it. Let's start by dividing our fraction in half:

\frac{22}{100} = \frac{11}{50}

Can we reduce that any more? No, because 11 can not be divided by anything else.

If you want the first fraction, go with \frac{22}{100}, but if they want a reduced fraction, then \frac{11}{50} would be best.

Dafna11 [192]
The future amount of the current deposit given that the interest is simple and yearly is computed through the equation,
                                 F = P x (1 + in)
where P is the principal amount, F is the future amount, i is the interest (in decimal form) and n is the number of years.

In this certain problem, we substitute the known values to the equation and solve for P,
                             2419.60 = P x (1 + (0.052)(1)) 
                                       P = 2300
Thus, the initial investment was worth $2,300.
