Question

1. Verify the commutative property x × = y =y× x
1. x= 11/15 , y= 9/-16​

Answer 1

Step-by-step explanation:

LHS :

$\frac{11}{15} \times \frac{9}{( - 16)} \\ = \frac{11}{5} \times \frac{3}{( - 16)} \: (after \: cancelling \: 9 \: and \: 15 \: with \: 3) \\ = \frac{33}{( - 80)} = \frac{ - 33}{80}$

RHS :

$\frac{9}{( - 16)} \times \frac{11}{15} \\ = \frac{3}{( - 16)} \times \frac{11}{5} (aftr \: cancelling \: 9 \: and \: 15 \: with \: 3) \\ = \frac{33}{( - 80)} = \frac{ - 33}{80}$

LHS = RHS

so therefore, Commutative propert for multiplication is verified
