735除以十五的教程

735÷15的竖式

1029

735/15=49

735*15*6 =735*(15*6) =735*90 =66150

735÷15=735÷(5x3)=735÷5÷3=147÷3=49,你好,本题已解答,如果满意请点右下角“采纳答案”.

735÷15*6= 735*6÷15= 4410÷15= 294用的是交换律,还有,说下,“乘以”这种说法是不对的,通常说“乘”

(1)735÷15*7 =49*7=343;(2)(704+258)÷37=962÷37=26;(3)900-600÷30=900-20=880;(4)420÷70*254=6*254=1524;(5)18*(537-488)=18*49=882;(6)635-(125+68)=635-193=442.

(1)800-600÷20, =800-30, =770; (2)18*(537-488), =18*49, =18*(50-1), =18*50-18, =900-18, =882; (3)39*101, =39*(100+1), =39*100+39, =3939; (4)735÷15*6, =49*6, =294; (5)75*299+75, =75*(299+1), =75*300, =22500; (6)720÷16÷5, =720÷(16*5), =720÷80, =9.

735÷15*6=735÷5÷3*6=(735÷5)*(6÷3)=147*2=294

呵呵,等于1029啦,735除以15等于49再乘以21就是1029了.
