〔29.5+32.6〕*47.8+62.1*52.5怎样简算?〔29.5+32.6〕*47.8+62.1*52.5怎样简算?〔29.5+32.6〕*47.8+62.1*52.5怎样简算?〔29.5+3

〔29.5+32.6〕*47.8+62.1*52.5怎样简算?
〔29.5+32.6〕*47.8+62.1*52.5怎样简算?

〔29.5+32.6〕*47.8+62.1*52.5怎样简算?
〔29.5+32.6〕*47.8+62.1*52.5=62.1*47.8+62.1*52.5=62.1*(47.8+52.5)
估计52.5写错了,应该是52.2
这样的话
62.1*(47.8+52.2)=6210

(29.5+32.6)*47.8+62.1*52.5
=62.1*47.8+62.1*52.5
=62.1*(48.8+52.5)
=62.1*101.3
然后笔算
