Solution: The least common multiple of 3 and 4 is 12.

1/3 = 4/ 12

1/4 = 3/ 12

Then the scores are 4/ 12 and 3/ 12.

Definition of total score

According to the basic properties of fractions (formulas), the process of converting several fractions (formulas) with different denominators into fractions (formulas) with the same denominator is called total score.

Reduction is fractional reduction. The numerator and denominator of the fraction are divided by the common factor at the same time, and the value of the fraction remains unchanged. This process is called reduction, and the basis of reduction is the basic properties of fractions.

Method 1: You can divide by the common factor of numerator denominator (except 1).

Example:

rule

Is the simplest score.

In this way, turning a fraction into a fraction equal to it, but with smaller numerator and denominator, is called a reduced fraction (generally it should be turned into the simplest fraction).

Method 2: directly use the greatest common factor of the numerator denominator of the fraction (except 1) to remove it.

Example:

rule

Is the simplest score.

Simplify:

Generally speaking, it refers to the process of transforming complex equations into simple equations in physical chemistry, mathematics and other science and engineering.

Fractionation is called reduction for short.

Simplification of algebraic expressions includes shifting terms, merging similar terms and removing brackets. Simplified formula is generally the simplest formula, and the number of items is reduced.

Solving equations can also be regarded as a simplified process.

For example: 1, 3a+a=4a 2, 2a+4=2(a+2).
