Huu hapa ni ufumbuzi wa swali la 11: Tunapewa usemi ( - )/( + 2 ) na kwamba = (8)/(15). Step 1: Gawanya kila neno katika namba (numerator) na denomineta (denominator) kwa . Hii itaturuhusu kutumia thamani ya . ( )/( ) - ( )/( )( )/( ) + (2 )/( ) Tunajua kuwa ( )/( ) = na ( )/( ) = 1. Hivyo usemi unakuwa: ( - 1)/( + 2) Step 2: Badilisha thamani ya = (8)/(15) kwenye usemi. (8)/(15) - 1(8)/(15) + 2 Step 3: Rahisisha namba na denomineta. Kwa namba: (8)/(15) - 1 = (8)/(15) - (15)/(15) = (8 - 15)/(15) = (-7)/(15) Kwa denomineta: (8)/(15) + 2 = (8)/(15) + (30)/(15) = (8 + 30)/(15) = (38)/(15) Step 4: Gawanya namba kwa denomineta. (-7)/(15)(38)/(15) = (-7)/(15) × (15)/(38) Futa 15 kutoka namba na denomineta: (-7)/(38) Jibu la mwisho ni: -(7)/(38) Tuma swali linalofuata 📸
