This can be done by actually solving the operation 15/4:
15/4 = <u><em>3 3/4</em></u>
If you were to actually put in fifteen divided by four into a calculator, it would probably give you 3.75, which is equivalent to 3 3/4.
Hope this helps!

The amount of the radioactive substance is 374.6 g
<h3>How to determine the amount of
radioactive substance?</h3>
The given parameters are:
- Initial, a = 424 mg
- Rate, r = 6%
- Time, t = 2 hours
The amount of the radioactive substance is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 424 * (1 - 6%)^t
At 2 hours, we have:
A(2) = 424 * (1 - 6%)^2
Evaluate
A(2) = 374.6
Hence, the amount of the radioactive substance is 374.6 g
