When we see a group of objects we usely group them and count the ones of the same group. In groups there should be same objects or assumedly
same objects.
Have also a look at ry1.
The question is just to remind of the importance of unit fraction ... .
This operation is called fraction expansion .
6/14 and 66/140 both can not be !
52/8 is not a natural number .
With choice III the word "commmon" fails .
Gitche Manito, the mighty, The creator of the nations,
Looked upon them with compassion, With paternal love and pity;
Looked upon their wrath and wrangling But as quarrels among children,
But as feuds and fights of children!
Over them he stretched his right hand,
To subdue their stubborn natures, To allay their thirst and fever,
By the shadow of his right hand; Spake to them with voice majestic
As the sound of far-off waters, Falling into deep abysses,
Warning, chiding, spake in this wise:--
"O my children! my poor children!
Considering 1 as prime and prime factor is not convenient, may result in never ending loops in case of machine calculations.
In case you have difficulties with statement IV, go to the next question before answering .
As factors we must have :
I- All factors that are not common.
II- The maximal number of common factors from only one of the numbers .
The common factors are 2 and 3 .
The number of repetitions is 2 for 2 and 1 for 3. Maximum no. of repetition for 2 is 2.
We get only 2x2 from 12 or 132 and not from both of them. So we get 2x2 instead of (2x2) x (2x2)
Considering 1 as prime may lead to inconveniencies.
Since the fractions are not in their simplest forms, not reduced, the least common multiple (LCM) and the least ccommon divisor (LCD) are
not the same .
Definitions are very important they must be as complete as possible. There are lots of numbers that can divide (not evenly) and does not
reduce.
Under divisor a number that divides without remainder is understood.
Listen to the words of wisdom,Listen to the words of warning,
From the lips of the Great Spirit,
From the Master of Life, who made you!
"I have given you lands to hunt in,
I have given you streams to fish in,
I have given you bear and bison,I have given you roe and reindeer,
I have given you brant and beaver,
Filled the marshes full of wild-fowl,
Filled the rivers full of fishes: Why then are you not contented?
Why then will you hunt each other? "I am weary of your quarrels,
In case of GCD the minimal repeating common prime factors are considered. If 2 is a common prime factor and repeats thrice in one of the
numbers and twice in the other, 2x2 is used in multiplicaiton of prime factors.
Reduce first 30/108 via GCD to get 5/18.
The LCM of 3/4 and 7/36 is 36 .
9/36 is 1/4 and 1/4+3/4 is 1 .
8 is the LCD
This time LCD is 18 .
70 is common denom.
common denom is 2x2x2x3x3x5x7 .
So a relatively hard question is divided into parts and solved.
The numerator is constant and the denominator is decreased by division by 2.
ry1 shows that the whole area will ultimately be covered and the total area, unit area, 1 , will be obtained.
