To find 75% of 60, you can use the expression:
\[ 0.75 \times 60 \]
However, if we break it down further, since 75% can also be expressed as \(1 - 0.25\) (which is 25%), we can calculate it as:
\[ 60 - (0.25 \times 60) \]
Thus, to find 75% of 60 using the options given, we need to calculate:
\[ (3) (15) \quad \text{or} \quad (0.75) (60) \quad \text{(which isn't listed)} \] This is because both expressions \( (3) (15) \) and \( (0.25) (60) \) can be evaluated to either the value of \( 75% \) of \( 60 \) or \( 25% \) of \( 60 \), followed by their subtraction from the whole \( 60 \).
In your case, but from your listed options specifically, only:
- \( (3)(15) \)
is correct since \( 3 \times 15 = 45\) is effectively \( 75%\) of \( 60 \).
