原式=14/15 ÷(4/5+2/3)×10/11
= 14/15 ÷(12/15+10/15)×10/11
= 14/15 ÷22/15×10/11
=14/15 ×15/22×10/11
=7/11×10/11
=70/121

14/15÷[(4/5十2/3)X10/11]=14/15÷[(12/15十10/15)X10/11]=l4/|5÷(22/|5Xl0/11)=|4/l5X3/4=7/10。

回答3:

14/15÷[(4/5+2/3)×10/11]
=14/15÷[(12/15+10/15)×10/11]
=14/15÷(22/15×10/11)
=14/15÷4/3
=14/15×3/4
=7/10

回答4:

14/15 ÷ [(4/5 +2/3) × 10/11]
= 14/15 ÷ [22/15 x 10/11]
= 14/15 ÷ 4/3
= 14/15 x 3/4
= 7/10
