7.26亿+8.69亿+38.23亿+8.51+0.32亿一共等于多少
7.26亿+8.69亿+38.23亿+8.51+0.32亿一共等于多少
7.26亿+8.69亿+38.23亿+8.51+0.32亿一共等于多少
7.26+8.69+38.23+8.51+0.32=62.6亿
答案是:
假如,8.51 是 8.51 亿
7.26+8.69+38.23+8.51+0.32
= (363/50) + (869/100) + (3823/100) +(851/100) + (8/25)
= (363/50)(2/2) + (869/100) + (3823/100) +(851/100) + (8/25)(4/4)
= (726/10...

答案是:
假如,8.51 是 8.51 亿
7.26+8.69+38.23+8.51+0.32
= (363/50) + (869/100) + (3823/100) +(851/100) + (8/25)
= (363/50)(2/2) + (869/100) + (3823/100) +(851/100) + (8/25)(4/4)
= (726/100) + (869/100) + (3823/100) +(851/100) + (32/100)
= (726 + 869 + 3823 +851 +32 )/100
= 6301/100
=63.01 亿
或者
假如,8.51 是 8.51 元 ,天啊
1元 = 1/(1*10^9) 亿元
8.51 元 = 8.51/(1*10^9) 亿元
7.26+8.69+38.23+8.51/(1*10^9) +0.32
= (726/100) + (869/100) + (3823/100) +(32/100) + 8.51/(1*10^9)
= (726/100) + (869/100) + (3823/100) +(32/100) + 8.51/(1*10^9)
= (5450 /100) + 8.51/(1*10^9)
=54.50000001 亿元
