解:4.5×(4+2.6)×6等于( 891/5 ),【即等于178.2】
∵已知需求出4.5×(4+2.6)×6等于多少
∴4.5 × (4 + 2.6) × 6
= (4×10+5)/10 × [4 + (2×10+6)/10]× 6
= 45/10 × (4 + 26/10)× 6
= 9/2 × (40/10 + 26/10)× 6
= 9/2 × 66/10 × 6
= 9/2 × 33/5 × 6
= 297/10 × 6
= 297/(5×2)× (3×2)/1
= (297×3)/5
= 891/5
= 178.2
答:4.5×(4+2.6)×6等于891/5,【即等于178.2】
