Check whether the given rational numbers are equal or not? 8 - 12 and - 10 15 .

Given , 8 - 12 and −10 15 By using cross multiplication, we get 8 × 15 = 120 and ( − 10 ) × ( − 12 ) = 120 ⇒ 8 × 15 = ( − 10 ) × ( − 12 ) So, 8 - 12 = −10 15 Hence, the given rational numbers are equal.

Check whether the given rational numbers are equal or not? - 8 - 14 and 15 21

Given, −8 - 14 , 15 21 By using cross multiplication, we get ( − 8 ) × 21 = − 168 and 15 × ( − 14 ) = − 210 Then, ( − 8 ) × 21 ≠ 15 × - 14 Hence, the given rational numbers are not equal.
