✔ 最佳答案
25.2X1.25=31.5升31.5/29.375X100%=107 47/11%
ANS:107 47/11%
依我所見你老師應該出錯左,根本走唔到去25.2km,硬計就係我上個ans,可能他last個幾km用行/入油again。

**(25.2×1.25)÷39.375×100%
OR
(25.2×1.25)÷29.375×100%
(25.2×1)÷39×100%=31.5÷29.375×100%
=(3150÷29.375)%
=107%(to 3 sig fig)
**(25.2×1.25)÷39.375×100%
=31.5÷39.375×100%
=(3150÷39.375)%
=80%
(25.2×1)÷39×100%
=25.2÷39×100%
=(2520÷39)%
=6460%(to 3 sig fig)
**我想是這个,80%才对

行25.2公里耗用多少汽油﹖
25.2x1.25=31.5升
有問題噃，入滿29.375升油行不了25.2公里﹗
何處出錯﹖
