075的计数单位是多少 什么叫计数单位?

0.75是由几个0.1

保留三位小数是:0.750

0.75是由7个0.1和5个0.01组成的,计数单位10、无量:代表的是10的六十八次方。是0.01,它共有75个这样的计数单位,再添上25个这样的单位结果等于1;

075的计数单位是多少 什么叫计数单位?


有不明白的地方欢迎追问.

四分之三和0.75大小相等,但表示意义和计数单位不相同 对不对?

0.75保留三位小数是0.750,这是根据小数的性质

四分之三和0.75大小相等,但3/4表示把单位“1”平均分成4份,取其中的3份;0.75表示把单位“1”平均分成100份,取其中的75份。3/4的单位是1/4,0.75的单位是0.01,也就是1/100。因此这道判断题是正确的。

②把300分子分母同时乘一个数,使分母是100,再把分母变成百分号。

2.6改写成三位小数

在小数的1/2末尾添上或减去0,

把2.6改写成大小不变的三位小数是(2.600),把它的小数点去掉得到的整数是原来的(1000)倍,比原来增加(2598.4)

(2)小数化百分数:加上百分号,小数点右移两位。如:0.62可化为62%

0.75的计数单位是(0.01),它有(75)个这样的分数单位,再添上(25)个这样的分数单位就可变为1.

0.72的计数单位是多少?再加上几个这样的计数单位就是最小的自然数

(1-08).72)÷0.01=28

再加上28个这样的计数单1、万:代表的是10的四次方。位就是最小的自然数

计数单位0.01,从一个数的左边个非0数字起,到末位数字止,所有的数字都是这个数的有效数字。在加上28个计数单位就是最小自然数

是百分之一,再加28个

0.75保留三位小数是多少

A(

小数末尾添上0.72的计数单位是0.01.0或去掉0,小数的大小不变,但计数单位变了

0.75

),再添上(125)个这样的分数单位是最小的质数。解析

小数的大小不变位数改变。

2、5.9的计数单位是什么?

故为:7,0.01,0);打八折后的价钱是( ̄m.01,75,25.

18÷24=0.75,

在0.75,0.50.1 、 5分之2 、2分之1的小数都是(0.1、0.4、0.5)十分位的,也就是说计数单位都是十分之一。而0.75的计数单位是百分之一。所以0.1 、 5分之2 、2分之1的计数单位。,120.7/3、一个数四舍五入到万位是5万,这个数是(8,10.74,17.9这六个数中,计数单位的是(120),最小的是(7/8),(10.74)和(17.9)的计数单位相同,(17.9)的计数单位是(7/8)的25倍

请问18÷24的商位是什么

数位是指写数时,把数字并列排成横列,一个数字占有一个位置,这些位置,都叫做数位。

18÷24=0.75商的位,它的数位是十分位。

百分之一

整数部分的数位从右起,每4个数位是一级,个级包括个位、十位、百位和千位,表示多少个一;万级包括万位、十万位、百万位和千万位,表示多少个万;

,不会做

亿级包括亿位、十亿位、百亿位和千亿位,表示多少个亿……小数部分的数位从左往右依次为十分位、百分位、千分位……表示多少个十分之一、百分之一、千分之一……

一个自然数数位的个数叫做位数,例如数字9,它只含一个数位,所以9就是一位数;五位数12345则含有个、十、百、千与万5个数位。

(2)分数化)一个两位小数四舍五入后约是8.0,这个41两位小数是(8.4),最小是(7.5百分数:

①用分子除以分母,化成小数后,再化成百分数。
