1.53 23.4 7.2简便计算

1.53+23.4÷7.2=1.53+3.25=(1+3)+(0.53+0.25)=4+0.78=4.78

1.53 +23.4÷7.2=1.53+23.4/7.2=1.53+78/24=1.53+26/8=1.53+3.25=4.78 谢谢,请采纳

1.53÷23.4÷7.2=153/2340*5/36=153/16848

2.53+23.4÷7.2=2.53+3.25=5.78没有简算,直接计算

(1)1 2 ÷[(5 8 ?1 2 )*1 3 ]=1 2 ÷[1 8 *1 3 ]=1 2 ÷1 24 =12;(2)(2 3 ?4 7 )*21+4 5 =2 3 *21?4 7 *21+4 5 =14-12+4 5 =2+4 5 =24 5 ;(3)(7?6*2 3 )÷7 9 =(7?4)÷7 9 =3÷7 9 =27 7 ;(4)(7 8 ?1 4 )÷(5 9 ?1 3 )=5 8 ÷2 9 =45 16 .

23.4*7.2+7.2=(23.7+1)*7.2=24.4*7.2=175.68

23.4-0.8-13.4-7.2=(23.4-13.4)-(0.8+7.2)=10-8=2 希望采纳,您的采纳是我们前进的动力

12.6加上23.4除以7.2的简便运算12.6+23.4÷7.2=12.6+3.25=15.82 直接计算

2.8x23.4+35.9x7.2=1.4x2x6.5x3.6+35.9x7.2=9.1x7.2+35.9x7.2=7.2x(9.1+35.9)=7.2x45=324

6.8乘0.75/0.5 =6.8*(0.75*2)=6.8*1.5=10.213.75/0.125-2.75 =13.75*8-2.75=110-2.75=107.251.53+23.4/7.2 =1.53+23.4÷9÷0.8=1.53+2.6÷0.8=1.53+3.25=4.782.85/1.25/0.8 =2.85÷(1.25*0.8)=2.8510.5*0.25*12=10.5*(12÷4)=10.5*3=31.5
