Question

Is {-6/ 7 + ( -9/ 14 ) } same as -6/ 7 + { ( -9/ 14 +7 ) } ? plzzz plzzz give me correct answer

Answer 1

No they are not same. As
= {-6/ 7 + ( -9/ 14 ) }
= - 6 / 7 - 9 / 14
= - 6 * 2 / 7 * 2 - 9 / 14
= - 12 / 14 - 9 / 14
= - 21 / 14
= - 3 / 2
Whereas
= -6 / 7 + { ( -9/ 14 +7 ) }
= -6 / 7 + { ( - 9 / 14 + 7 * 14 / 14 )}
= -6 / 7 + { ( - 9 / 14 + 98 / 14 )}
= -6 / 7 + {( 89 / 14)}
= -6 / 7 + 89 / 14
= -12 + 89 / 14
= 77 / 14
= 11 / 2
