To find 75% of 24, you can think of it as finding three-quarters of 24 because 75% is equivalent to three-quarters.
The expression Maxwell could have used is:
(Three-fourths) (24)
This calculates 75% of 24.
Alternatively, you could also find it by subtracting 25% (or one-fourth) of 24 from the total:
Since 25% of 24 is \( \frac{1}{4} \times 24 = 6 \), if you reduce 24 by 6 (which is 25% of 24), you would also get 75%. However, the most straightforward way is to directly use the three-quarters expression.
