प्रश्न

Verify the identity property for addition and multiplication for the rational numbers `15/19` and `(-18)/25`

बेरीज

उत्तर

`15/19 + 0 = 15/19 + 0/19`

= `(15 + 0)/19`

= `15/19`

`(-18)/25 + 0 = (-18)/25 + 0/25`

= `(-18 + 0)/25`

= `(-18)/25`

Identify property for addition verified.

`15/19 xx 1 = (15 xx 1)/19 = 15/19`

`(-18)/25 xx 1 = (-18 xx 1)/25 = (-18)/25`

Identify property for multiplication verified.
