Instruction
1. Multiply correct (written down as the numerator relation to a denominator) fraction and natural number: fraction numerator, or a dividend, increase by number and write down result in numerator (number which is located over horizontal line – a fraction divider). The denominator (divider) remains the same.
2. Multiply mixed (written down as a proper fraction and an integer) fraction and natural number: increase the whole part and numerator of fraction by this number, and leave a denominator without changes. The mixed fraction is the sum of the whole fraction and number.
3. Multiply two fractions among themselves: at first multiply among themselves numerators of fractions, and write down result in numerator, and then, respectively, multiply denominators and write down result in a denominator.
4. Multiply among themselves the mixed fractions: in the beginning write down fractions in the form of wrong in which the module of numerator is more than denominator module. For this purpose increase the whole part of fraction by a denominator and add the received work to number in numerator. After transformation multiply, respectively, numerators and denominators of fractions and write down result in the form of an improper fraction.
5. Divide one fraction into another: trade places numerator and a denominator in the second fraction – receive the return fraction and increase the received fraction by the first as it is described above.
