Question

Verify commutative property of multiplication if x = 2 and y =-7/8​

Answer 1

⠀⠀⠀Commutative Property

when two real numbers are given as a and b, then we can multiply them in any order to get the result.

• $\rm x =2$
• $\rm y =\large\frac{-\:7}{8}$

$\underline{\bigstar\:\boldsymbol{According\:to\:the\:Question :}}$

$:\implies\sf x \times y = y \times x\\\\\\:\implies\sf 2 \times \dfrac{-\:7}{8}=\dfrac{-\:7}{8} \times 2\\\\\\:\implies\sf \dfrac{- \:7}{4} = \dfrac{ - \:7}{4}\\\\\\:\implies\underline{\boxed{\sf - \:1.75 = - \:1.75}}$

$\rule{180}{2}$
