Fractions are a mathematical form of record of a prime rational number. It represents number which consists of one or several shares of unit, can be both in decimal, and in a usual look. Today operations on transformation of fractions have huge value not only in mathematics, but also in other fields of knowledge.
Instruction
1. As a rule, the majority of common fractions are wrong, and in that case they demand certain actions from the one who solves examples and problems with this fraction.
2. Take the textbook with the task. Attentively get acquainted with a condition, having read it several times, and pass to the decision. Look what fractions are available in the actions solved by you. It can be the improper, proper or decimal fractions. Transfer proper fractions to wrong, but at the same time you remember that for record of the answer all operations should be performed back, having transformed already improper fraction to correct. At an improper fraction the number over fractional line (numerator) is always more than number below the line – a denominator. To make the translation of a proper fraction in wrong it is necessary to follow these steps.
3. Increase a denominator by an integer and add numerator to the received result. For example, if fraction of a look 2 whole 7/9, it is necessary 9 to increase by 2 and then to 18 to add 7 - 25/9 will be the end result.
4. Make all necessary actions on the task (additions, subtraction, division, multiplication), using the transformed fractions. Take the answer, it will need to be presented in a common fraction. For this purpose divide numerator into a denominator. For example, if it is necessary to transfer number 25/9 to a proper fraction, divide 25 into 9. As 25 on 9 totally does not share, in the answer it turns out 2 whole and seven (numerator) of the ninth (denominator). Now the proper fraction where the numerator is more than a denominator is received and there is the whole part.
5. Write down the answer of a task a proper fraction. Carry out an inspection to the actions in case the statement of the problem or the teacher demands to make it.
