✔ 最佳答案

276×33又3分1

=276x100/3 (33又3分1=100/3)

=27600/3

=9200

註：先把帶分數的33又3分1化為假分數的100over3

其實lee題的確可以有技巧感去計
例如你知道 276係3既倍數[[p.s. "27"係3倍數,"6"都係]]
咁你就知要計就要將33又3分1,,,化做假分數
之後你知道33又3分1等於3分100,,,就好易計架啦~~~
276*100/3 [[p.s."27/3"=9,,,"6/3"=2... "276/3"=92]]
= 92*100
= 9200

276×33又3分1= 276×100分3
= (276×100分3)×3
=(276/3)×100
= 92×100
=9200

I hope i can help you

276*33=9108
276*1/3=92

9108+92=9200

or
276*100/3=9200
