2又25分之14等于什么分数

25分之14乘8+25分之17乘14
=25分之8×14+25分之17×14
=14×（25分之8+25分之17）
=14×1
=14

25分之14 小数(0.56 ) 百分数( 56%)

0.8x-2.4=6.4
即 0.8X=8.8
则 X= 8.8/0.8 = 11

7x/10=14/25 两边同时乘以50 并处以7 得到 ：
5X= 4 即X=0.8

A jet fighter points up to the sky, a row of missiles line a walkway and revolutionary films are on constant rotation at China's aviation museum on the outskirts of the capital, Beijing. Occupying pride of place here: the bomber which deployed China's first nuclear bomb.These are the relics of the Asian giant's military past, but it is also a nod to the might worthy of an emerging superpower.A red jet fighter catches my eye amid the Chairman Mao paintings: it is the MiG-15 credited with China's first victory in the sky, shooting down an enemy aircraft over the skies of Korea in 1950.Now, the world's attention is focused on a new Chinese jet fighter,Jordan Shoes, the J-20. Pictures of the radar-evading stealth plane have appeared in recent days, carrying out runway tests. It is the latest addition to China's growing military arsenal.Is China matching U.S. jet prowess?2009: China's military power Rare look inside Chinese military base 2009: China's military power concerns The photos of the fighter come on the eve of a visit to Beijing by U.S. Defense Secretary Robert Gates that begins on Sunday. It is yet another reminder that China is developing the military might to go along with its economic strength, though Pentagon officials insist it does not mean China has matched American air capabilities.At a briefing on Thursday, Chinese foreign ministry spokesman Hong Lei declined to comment on reports that China was testing the jet."China insists on a path of peaceful development," he said. "We have adopted a national defense policy that is defensive in nature and do not threaten any other countries. China has been an important force in maintaining regional and global peace."Some analysts see an emerging power-play between the U.S. and China for influence in the Pacific and resource-rich Central Asia. To some, it is shaping up as a 21st century "Great Game," a modern replay of the 19th century struggle for empire between the giants of the time, Great Britain and Russia."There's a dangerous dynamic emerging here,Air Jordan Shoes 1," says Russ Moses, a long-time China analyst. "China sees itself being encircled and its newfound power being contained in some way."China really doesn't know what to do with its power. It has a lot of newfound capability but it hasn't decided what it wants to do or where to project its power.--Analyst Russ Moses RELATED TOPICS China Hu Jintao Military Aircraft Technology China officially spent about $80 billion on its defense in 2010 -- but unofficially others put it much higher. The U.S. Defense Department estimates China's military spending at closer to $150 billion.China is certainly modernizing and upgrading its hardware. As well as the new aircraft,Authentic Jordan Shoes, it is expanding its navy's capabilities, re-fitting older Russian aircraft carriers as well as building new ones.Moses says there is intense competition within the Chinese defense force for power and money. Each arm of the military wants to establish its own supremacy and outbid the other. This comes at a time when China is preparing for a leadership change with President Hu Jintao to begin his exit next year. His successor is widely believed to be Vice-President Xi Jinping.All of this makes the U.S., and regional powers like South Korea and Japan, wary. Moses says their concerns may be premature."China really doesn't know what to do with its power. It has a lot of newfound capability but it hasn't decided what it wants to do or where to project its power."Still, walking around the discarded jet fighters and bombers, the missiles and relics of war at the aviation museum, it is clear that military might was essential to China's past as it will likely be to its future.There are flashpoints: China's support for North Korea, the status of Taiwan,Nike Air Jordan Shoes, disputed islands with Japan. With Gates in Beijing over the weekend and China's President Hu Jintao preparing for his trip to Washington for talks with President Obama in late January,Buy Air Jordan 2, military matters are likely to be front and center."China is a rising power, and it is determined to challenge the American position globally," said China military scholar and author Richard Fisher.

因为数学分子分母用这个不好表示,所以就用汉语给你写的,

11/20×9/25+14/25×9/20

也点个赞把

64/25=2.56

把小数化为分数,再通分

一个分数乘15分之7和25分之14积都是整数,
说明这个分数的分子是15和25的最小公倍数,即75,
这个分数的分母是7和14的最小公倍数,即14,
所以说这个分数是75/14.
即14分之75

25分之14除以35
=14/25x1/35
=2/125
13分之9除以6
=9/13x1/6
=3/26
27分之23除以11
=23/27x1/11
=23/297

10分之7

1、设该分数为X/Y,则满足不等式组 7*(X+2)=4Y
{14X=25(Y_2)
解不等式组可分别得X和Y的值,然后通过X/Y得出该分数
2、假设原来的两位数是10x+y(xy都是个位数~并且x不等于0)
那么新数就应该是100x+y
所以由题意~得到9(10x+y)=100x+y(9代表大8倍)
所以5x=4y
因为x和y都是整数~所以只能是x=4~y=5
所以这个数是45~新数是405~
3、设甲是x,乙是110-x
x/5+（110-x）/4=25
4x+110*5-5x=25*20
x=550-500
x=50
乙=110-50=60

友情提醒：
同学,你的提问方式应当改一下,因为：
第一：整理下问题,老师看起来很乱的,分不清
第二：有些题描述的不是很清楚
如果未解决的话,请重新整理下,
你可以选择分块问.
祝你学业进步!
【我知道,因为你知道!
