Long division involves repeatedly dividing, multiplying, subtracting, and bringing down remaining digits. Specifically, the steps are: 1) Divide the dividend by the divisor to find the quotient, 2) Multiply the divisor by the quotient, 3) Subtract to find the remainder, 4) Check that the remainder is smaller than the divisor, and 5) Bring down remaining digits and repeat the process until there is no remainder. The document provides examples of working through long division problems step-by-step and reviews the key steps.
Long division is a method for dividing one number by another. It involves repeatedly subtracting the divisor from the dividend. The key steps are: (1) divide - determine how many times the divisor goes into the first digit of the dividend; (2) multiply - multiply the divisor by the answer; (3) subtract - subtract the product from the dividend; (4) bring down - bring down the next digit if there are any remaining; (5) repeat steps 1-4 or take the remainder. For example, in the long division problem 56/5, the steps are followed to get an answer of 11 with a remainder of 1.
To round a decimal number to the nearest whole number, look at the digit in the tenths column. If the tenths digit is 0-4, round down. If it is 5-9, round up. However, if rounding up results in the units digit becoming a 9 (e.g. 9.57), round up to the next multiple of ten instead of just the units place (e.g. rounding 9.57 up to 10 instead of 9).

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

We are dividing by 15, so I
am going to write down
the times tables for 15.
You will see why in a
minute!
15 30 45 60 75 90 105 120 135
15 into 1 won’t go (it goes 0 times) So put a ‘0’ above the (1).

Write the number 15 under the sum you have just worked out (19). You
write 15 because you need to find the remainder.
