Help with adding mixed fractions

Introduction to adding mixed fractions:
A mixed number is the sum of a whole numbers and a proper fraction. This sum is implied without the use of any visible operators such as "+"; for example, in referring to two entire cakes and three quarters of another cake, the whole and fractional parts of the number are written next to each other:

2+(3/4) = 2 ( 3/4)

Add the following mixed fraction numbers
3 (2/3) + 2 (1/3)
Solution:
First we have to convert mixed numbers to normal fraction
Take a first number
= (3*3) +2 / (3)
Simplify the above equation we get
= (11/3)
Similarly take the second term
= (2*3) +1 / (3). This could also help us on logic definition
= (7/3)
Compare the two fraction denominators both are equal so add the numerator directly
= (11+7) / 3
= (18/3)
The fraction is simplified and get 6

Help in calculating mean

How to calculate mean

In this session let me help you on what is mean.Mean, median and mode are more common terms in statistics.

The average or mean is calculated by arranging the value from the set in a particular way and computing a single number as being the average of the set.

The median of a list of numbers can be arranging all the values from lowest value to highest value and select the middle one.

Mode is also a compute of central tendency. In a set of individual observations, the value occurs most time is called as mode.

Mean

In general Arithmetic mean (A.M) or average of n number of data x1, x2, …, xn is defined to be the number x such that the sum of the deviations of the observations from x is 0. That is, the arithmetic mean x of n observations x1, x2, …, xn is given by the equation. This will also help us on perimeter of a triangle. This could also help us on normal distribution calculator.

(x1 − x) +(x2 − x) + … +(xn − x) = 0

Hence [barx] = x1+x2+x3+…….xn / n

Mean or average= sum of elements / total number of elements

Ex : To find the mean or average of 7, 5, 6

Step 1: Find the sum of numbers

7+5+6= 18

Step 2: Calculate the total value. Therefore 3 values

Step 3: Calculate mean use formula 18/3=6

Help with multiply exponents


Multiply Exponents

multiply this variable with exponents:
(x2)(x3)
So that x2 = xx, and x3 = xxx so that all the multiplies,
(x2)(x3)
= xxxxx
That is 5 "x"s multiplied mutually so the new exponent must be 5:
x2x3
= x5.
The exponents say to that there are two "x"s multiplied by 3 "x"s for a total of 5 "x"s: This could also help us on multiplication tables chart
x2x3
= x2+3 =x5
So, the simplest method is to just add the components

Ratio problems

Introduction for practice ratio problems:

In mathematics, a ratio expresses the magnitude of quantitie relative to each other. Specifically, the ratio of two quantities also indicates how many times the first quantity is contained in the second and may be expressed algebraically as their quotient. Example: For every Spoons of sugar, you need 2 spoons of flour (1:2)

In our daily life, by studying ratio and proportion many a times we compare two quantities of the same type. Thus, in convinced situation, comparison by division makes better sense than comparison by taking the difference. This could also help us on angle of inclination. The comparison by division is the Ratio. We denote ratio-using symbol ‘:’ . This could also help us on Introduction to proper fraction. If two ratios are equal, we state that they are in proportions and use the symbol ‘:’ or ‘=’ to equate the two ratios.

list of primes

Prime Numbers
In this section let me help you on list of primes. If a number does not have a factor beside 1 and itself, it is called prime.
Example :5 has no factor, whole numbers that can be divided by evenly, besides 1 and 5. It is therefore prime.20, and the other hand, the factors 1, 2, 4, 5, 10 and 20. Because it has factors beside 1 and itself (2, 4, 5 and 10), it is not prime.
Numbers that are not prime is called composite. 20 is a composite number.
Examples of prime numbers are 2, 3, 5, 7, 11 and 13.

Prime Factor:
The Factors are number you multiply to get other number. For instance , the factor of 15 are 5 and 3, because 5×3 = 15. Some numbers are more than one factors (more than one way of being factorization).This could also help us on date calculator number of days. For instance , 12 can be factored as the 1×12, 2×6, or 3×4. The number that can only be factors as 1 times itself is called prime. The few primes numbers are 2, 3, 5, 7, 11, and 13. The number 1 is not regards as to a prime, and is usually not included in factorizations.
