Ding Ding and his father went to visit his uncle who lived in Yangjiang. The uncle went fishing and harvested a salmon with a length of 0.64 meters. My aunt cut off the 0.18-meter-long fish head to make pan-fried fish head, then cut off the 0.12-meter-long fish tail to cook porridge, and made the rest to make Ding Ding’s favorite salmon sashimi. How long is the rest of the fish?
丁丁和爸爸去看望住在阳江的大伯，大伯出海打渔，收获了一条长0.64米的三文鱼．伯母切下长0.18米的鱼头做香煎鱼头，再切下0.12米长的鱼尾煲粥，余下的做丁丁最喜欢吃的三文鱼刺身．请问余下的鱼身长多少米？
