Visualizing Addition of Dissimilar Fractions Without and With Regrouping
Objective: Visualize addition of dissimilar fractions without and with regrouping.

Mother has one whole cake. First she sliced 1 and then 1 of the cake. What part of the cake did she slice? 2 4 Let’s solve the problem following the steps in problem solving.
1. What is asked for?
The part of the cake that was sliced.
2. What are the given data?
1 was the first sliced , and 1 was the second sliced 2 4 3. What is the mathematical sentence?
1 + 1 = n

2 4
1
4
1
2
1
8

4. So 1 + 1 = 3
2 4 4
* How can we add fractions if they are dissimilar?
* Change the fractions to similar then add.

...valuable support to me during the courses of this project. To begin with, I would
like to offer my sincere thanks to “Mr. Sanjith Menon , Executive Industrial Engineer”
for giving me the opportunity to do my summer internship at “Apollo Tyres”. Without his
guidance , support and valuable suggestions during the research, project would not have been
accomplished.
My heartfelt gratitude also goes to the entire “Apollo Process incharge” team for their cooperation and...
...Fraction (mathematics)
A fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, onehalf, eightfifths, threequarters. A common, vulgar, or simple fraction (examples: \tfrac{1}{2} and 17/3) consists of an integer numerator, displayed above a line (or before a...

The problem here is to add and 
These two fractions do not have the same denominators (lower numbers), so we must first find a common denominator of the two fractions, before adding them together.
For the denominators here, the 8 and 14, a common denominator for both is 56.
With the common denominator, the
becomes a
and the
becomes a
So now our addition problem becomes this...

* When land is polluted, it directly or indirectly affects the climate patterns.
3. Environmental Impact
* To begin with, the green cover is reduced. Trees and plants help balance the atmosphere, without them we are subjected to various concerns like Global warming, the green house effect, irregular rainfall and flash floods among other imbalances.
4. Effect on human health
* The land when contaminated with toxic chemicals...

A. Changing a Mixed Number to an Improper Fraction
Mixed number – 4 (contains a whole number and a fraction)
Improper fraction  (numerator is larger than denominator)
Step 1 – Multiply the denominator and the whole number
Step 2 – Add this answer to the numerator; this becomes the new numerator
Step 3 – Carry the original denominator over
Example #1: 3 =...
...Meanwhile, the law of attraction (Byrne, 1971) holds that the more
similar attitudes people have in common then the more they will like each
other. Cults encourage the fallacious notion that all members are more alike
than they really are, and are more dissimilar from nonmembers than is actually the case (Tourish & Wohlforth, 2000). The clear objective is to create an
overwhelming sense of group identity, infused with a spirit of cohesion,
loyalty and commitment to the group’s...
...Addiction
On April 25, 2013 Mr. Johnny Blakeage 32 African American male and middle class citizen had an appointment about some sexual preference and other issues that turned into addictions in Mr. Blake’s life.
