7/4÷(1/3)+15÷(11/13)+3/2等于用简便方法计算求过程
解:
原式=7/4÷(1/3)+15÷(11/13)+3/2
=7/4x3+15x13/11+3/2
=21/4+195/11+1+1/2
=5+1/4+17+8/11+1+1/2
=(5+17+1)+(1/4+2/4+8/11)
=23+(3/4+8/11)
=23+(33/44+32/44)
=23+65/44
=24又21/44
7/4÷(1/3)+15÷(11/13)+3/2等于用简便方法计算求过程
7/4*3+15*13/11+3/2
=21/4+195/11+3/2
=5+1/4+17+8/11+1+1/2
=23+1/4+8/11+1/2
=23+11/44+32/44+22/44
=23+65/44
=24(21/44)
结果就是24又21/44.望采纳!!!
7/4÷(1/3)+15÷(11/13)+3/2
=21/4+195/11+3/2
=21/4+6/4+195/11
=27/4+195/11
=6+3/4+17+8/11
=23+33/44+32/44
=23+1+21/44
=24又44分之21
