大家好,我是小环,我来为大家解答以上问题。初中角度分秒换算,度分秒换算很多人还不知道,现在让我们一起来看看吧!
1、2/3×16°47′30〃 =(16°+47′+30〃)*2/3 =(15°+1°+47′+30〃)*2/3 =15°*2/3+(1°+47′+30〃)*2/3 =10°+(107′+30〃)*2/3 =10°+(105′+2′+30〃)*2/3 =10°+105′*2/3+(2′+30〃)*2/3 =10°+70′+150〃*2/3 =11°+10′+100〃 =11°+20′+40〃 =11°20′40〃 18°÷7 = (14°+4°)÷7 =14°÷7+4°÷7 =2°+240′÷7 =2°+34′ =2°34′。
本文到此讲解完毕了,希望对大家有帮助。
