Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

exercise.

This captures the small-core of concept in simple-plain English. The objective is to make the learner to think about. continue

Trekking is bit hard, requiring one to sweat and exert. The benefits of taking the steps are awesome. In the trek, concepts are explained with exploratory questions and your thinking process is honed step by step. continue

This captures the essence of learning and helps one to review at a later point. The reference is available in pdf document too. This is designed to be viewed in a smart-phone screen. continue

This part does not have much content as of now. Over time, when resources are available, this section will have curated and exam-prep focused questions to test your knowledge. continue

Addition of Fractions

» Convert the fractions to like fractions and add numerators

→ subtraction is inverse of addition

`color(coral)(3/4) + color(darkgreen)(2/3)`

`= color(coral)(9/12) + color(darkgreen)(8/12)`

`= 17/12`

Addition of two fractions having different place values or denominator is explained.

Starting on learning "Addition of Fractions". ;; Addition of two fractions having different place values or denominator is explained.

Given two fractions in two colors in the figure. What is the sum of these?

- sum is not `3+2` as the parts are in different sizes
- the sum is `5` pieces

The answer is 'sum is not `3+2` as the parts are in different sizes'. This means that the place values are different.

Given two fractions `3/8` and `2/8` in the figure, what is the sum?

- sum is not `3+2` as the parts are in different sizes
- the sum is `5/8`

The answer is 'the sum is `5/8`'. The fractions have identical place values and so the numerators are added.

Given two fractions `1/4` and `3/8` in the figure, what is the sum?

- addition is not possible as the parts are different
- convert them to like fractions to add

The answer is 'converting them to like fractions to add'.

Given two fractions `1/4` and `3/8` in the figure, the fraction `1/4` is converted to equivalent fraction `2/8`. What is the sum of `1/4` and `3/8`?

- addition is not possible
- the sum is `5/8`

The answer is 'sum is `5/8`'.

The sum is calculates as `2/8 + 3/8 = 5/8`

**Addition or Subtraction of Fractions: ** Given `p/q` and `l/m`, to add or subtract, convert the fractions to like fractions with modified place value `(p xx i)/(q xx i)` and `(l xx j)/(m xx j)`. The numerators of the like fractions can be added and result is in the modified place value. `((p xx i) + (l xx j))/(text(LCM)(q,m))`

Given two fractions in two colors in the figure. What is the sum of these?

not;possible;parts

sum is not 3+2 as the parts are in different sizes

5;pieces

the sum is 5 pieces

The answer is 'sum is not 3+2 as the parts are in different sizes'. This means that the place values are different.

Given two fractions 3 by 8 and 2 by 8 in the figure, what is the sum?

not;possible;parts

sum is not 3+2 as the parts are in different sizes

sum;5

the sum is 5/8

The answer is 'the sum is 5/8 '. The fractions have identical place values and so the numerators are added.

Given two fractions 1 by 4 and 3 by 8 in the figure, what is the sum?

convert them to like fractions to add

The answer is 'converting them to like fractions to add'.

Given two fractions 1 by 4 and 3 by 8 in the figure, the fraction 1 by 4 is converted to equivalent fraction 2 by 8. What is the sum of 1 by 4 and 3 by 8?

addition;not;possible

addition is not possible

sum;5;8

The sum is 5 by 8

The answer is sum is 5 by 8. The sum is calculated as 2 by 8 plus 3 by 8 equals 5 by 8.

Convert the fractions to like fractions (having same place value) to add or subtract numerators.

Addition or Subtraction of Fractions: Given p by q and l by m, to add or subtract, convert the fractions to like fractions with modified place value p times i by q times i, and, l times j by m by j. ;; The numerators of the like fractions can be added and result is in the modified place value. p times i plus l times j by L C M of q and m.
