10. LOGICAL SEQUENCE AND COMPARISON OF DECIMAL FRACTIONS

10.1 Work together with a friend and compare the results of the following athletes.

Put the athletes in order from the winner to the last place.

 Name Long Jump Position High Jump Position Alec 6,1 m ................... 1,63 m ................... Dimitri 4,85 m ................... 1,5 m ................... Owen 5,9 m ................... 1,11 m ................... Tembo 5,32 m ................... 1,6 m ................... Vera 5,09 m ................... 1,23 m ................... Cindy 4,9 m ................... 1,57 m ................... Sonia 6,04 m ................... 1,7 m ................... Gloria 5,21 m ................... 1,34 m ...................

10.2 a) Find the following statistics of five of your class mates and complete the table:

 Name Height Mass 1. .................................................. .................... .................... 2. .................................................. .................... .................... 3. .................................................. .................... .................... 4. .................................................. .................... .................... 5. .................................................. .................... ....................

b) Arrange names of your friends from the shortest to the tallest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

c) Now arrange names of your friends from the heaviest to the lightest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

10.3 Fill in:<;>or = :

a) 0,63 …… 0,7

b) 0,4 …… 0,39

c) 32,068 …… 32,102

d) 1,27 …… 1,270

e) 0,007 …… 0,07

f) 4,44 …… 4,044

## Assessment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.3: We know this when the learner recognises, classifies and presents the following numbers in order to describe and compare them:

1.3.2 decimal (to at least three decimal places), fractions and percentages;

Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.

Assessment Standard 2.3: We know this when the learner represents and uses relationships between variables in a variety of ways using:

2.3.3 tables.

Learning Outcome 5: The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.7: We know this when the learner identifies the largest and smallest scores in a data set and determines the difference between them in order to determine the spread of the data (range).

where we get a research paper on Nano chemistry....?
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what is variations in raman spectra for nanomaterials
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
