Question

62.3×1.7+2.3×1.7脱式怎么计算？

Answer 1

解：62.3×1.7+2.3×1.7等于（ 5491/50 ），【即等于109.82】
∵已知需求出62.3×1.7+2.3×1.7等于多少
A × B + A × C = A × （B + C）
∴62.3 × 1.7 + 2.3 × 1.7
= 1.7 × （62.3 + 2.3）
= （1×10+7）/10 × [（62×10+3）/10 + (2×10+3)/10]
= 17/10 × （623/10 + 23/10）
= 17/10 × 646/10
= 17/10 × 323/5
= 5491/50
= 109.82
答：62.3×1.7+2.3×1.7等于5491/50，【即等于109.82】

Answer 2

62.3×1.7+2.3×1.7
=105.91+3.91
=109.82

Answer 3

62.3×1.7+2.3×1.7
＝(62.3+2.3)×1.7
＝64.6×1.7
＝109.82
62.3×1.7-2.3×1.7
＝(62.3-2.3)×1.7
＝60×1.7
＝102
