Solution

The correct option is D $7 + \frac{13}{2} = \frac{13}{2} + 7$
$Given numbers: 7 and \frac{13}{2} Let a = 7 and b = \frac{13}{2}$

$Commutativity of addition states that, a + b = b + a \Rightarrow 7 + \frac{13}{2} = \frac{13}{2} + 7$

$Commutativity of multiplication states that a \times b = b \times a \Rightarrow 7 \times \frac{13}{2} = \frac{13}{2} \times 7$
