7.6×3/14加17.5×6/25用简便方法计算

7.6×3/14+17.5×6/25 =11.4/7+21/5 =(11.5*5+21*7)/35 =(57.5+147)/35 =204.5/35 =409/70

解: 原式=35.4-25.5+14.6-14.2 =(35.4+14.6)-(25.5+14.2) =50-39.7 = 10.3

37.6减(7.6加3.25)怎样用简便方法计算? 37.6减(7.6加3.25) =37.6-7.6-3.25 =30-3.25 =26.75

8/5×7+8/1×5 =8/5×(7+1) =8/5×8 =5 6/5×25-6/1×85 =6/5×(25-17) =6/5×8 =3/20

4.75+3.25×2.4+7.6 =4.75+7.8+7.6 =12.55+7.6 =20.15 没有更简便的方法

您好: 24*【(7/6-3/20)/3】 =24÷3x(70/60-9/60) =8x61/60 =8x1+8x60 =1又2/15 3.25-2.8*5/7+1/4*4/7/.01 =3.25-2+1/7x10 =1.25+10/7 =5/4+10/7 =75/28 如果本题有什么不明白可以追问,如果满意记得采纳 如果有其他问题请采纳本题后另发点击向...

4.75+3.25×2.4+7.6 =4.75+2.25×2.4+1×2.4+7.6 =4.75+0.25×9×0.4×6+(2.4+7.6) =4.75+(0.25×0.4)×(9×6)+10 =14.75+0.1×54 =14.75+5.4 =20.15

用简便计算3点75乘0点5加6点25除以2 3.75x0.5+6.25÷2 =3.75x0.5+6.25x0.5 =(3.75+6.25)x0.5 =10x0.5 =5

您好,寒樱暖暖为你解答: 3.5÷4+360×25%+0.25×36.5 =3.5×0.25+360×0.25+0.25×36.5 =0.25×(3.5+360+36.5) =0.25×400.1 =0.25×(400+0.1) =0.25×400+0.25 =100+0.25 =100.25 如果你认可我的回答, 请及时点击【采纳为满意回答】按钮,(或在客...
