To evaluate the expression \( 4 \frac{7}{2} \), first convert the mixed number into an improper fraction. The mixed number can be expressed as \( 4 + \frac{7}{2} \). We can rewrite 4 as \( \frac{8}{2} \) so that both parts have the same denominator. Thus, we have: \[ \frac{8}{2} + \frac{7}{2} = \frac{8 + 7}{2} = \frac{15}{2} \] Now, if we multiply 4 by this fraction, we multiply 4 (or \( \frac{8}{2} \)) by \( \frac{7}{2} \): \[ 4 \cdot \frac{7}{2} = \frac{28}{2} = 14 \] So, the evaluation leads to the final answer: \( \frac{28}{2} = 14 \), which is not present in the options A, B, C, or D provided. It seems that something may have been misinterpreted in how the numbers were presented. Based on the choices provided, the calculation directs that this specific format might not have intended to give whole or integer values. Please check the expression again or the options provided.
