1/2 x 4/3 + 5/6 divided by 7/8
To solve the expression 1/2 * 4/3 + 5/6 divided by 7/8, you should follow the order of operations (PEMDAS/BODMAS).
First, simplify the multiplication: 1/2 * 4/3 = 4/6 = 2/3
Next, simplify the division: 5/6 ÷ 7/8 = 5/6 * 8/7 = 40/42 = 20/21
Finally, add the results: 2/3 + 20/21 = (14/21) + (20/21) = 34/21
Therefore, the result is 34/21 or 1 13/21.
Why is western china non-cultivated? Why is agriculture production in china have the western china non-cultivated.
There are several reasons why parts of western China are non-cultivated and have lower agricultural production compared to other regions in China. Some of these reasons include:
1. Geographic Factors: Western China consists of vast mountainous terrains, plateaus, and desert regions, such as the Tibetan Plateau and the Taklamakan Desert. These geographic factors make it challenging for agriculture due to limited fertile land, harsh terrain, and extreme weather conditions.
2. Climate Conditions: Western China experiences a wide range of climates, including arid, semi-arid, and alpine climates. The arid and semi-arid regions have limited water resources, high evaporation rates, and low rainfall, which make it difficult for agriculture. The cold temperatures in alpine regions are not conducive to growing crops.
3. Lack of Infrastructure: The development of infrastructure, such as irrigation systems, transportation networks, and access to markets, is relatively limited in some parts of western China. This hinders the growth and expansion of agriculture in these regions.
4. Cultural and Ethnic Factors: Western China is home to various ethnic minority groups with their own cultural practices and traditions. Some of these groups have traditionally relied on pastoralism, nomadic herding, or other livelihoods besides agriculture as their main source of sustenance.
5. Government Policies: Historically, the Chinese government has focused its agricultural investments and policies on the more populous and economically prosperous regions in eastern China. This has resulted in disparities and relatively lower levels of agricultural development in western China.
It's important to note that while agricultural production may be lower in some parts of western China, the region has its own unique ecosystems, valuable natural resources, and cultural diversity that contribute to its overall significance for China. Efforts are being made to promote sustainable agriculture practices and improve agricultural productivity in western China through various policies and initiatives.
A: much of western china is covered by dense rain forests,
B: much of western china is mountainous and has a desert climate.
C: the Huang He frequently floods, destroying farmland in western china,
D: The Gobi Desert covers western china, making it incapable of supporting farms.
I apologize for the incorrect information in my previous response. Let me correct it:
B: Much of western China is mountainous and has a desert climate.
D: The Gobi Desert covers parts of western China, which makes it challenging to support agricultural activities.
While there are some areas of western China that have dense rainforests, such as the Yunnan and Sichuan provinces, they are not representative of the entire western region. The statement A about dense rainforests covering much of western China is not accurate.
Regarding statement C, the Huang He (Yellow River) does pass through western China, but its frequent flooding mostly affects the central and eastern regions of the country, not specifically western China. Flooding can indeed damage farmland, but it is not a primary reason for non-cultivation in western China.
In summary, the mountainous terrain, desertification, and limited water resources, including the presence of the Gobi Desert, are primary factors that limit agricultural production in parts of western China.
