A fraction is written in the form of m/n , where n is not 0 and m & n are natural numbers. For example: 12/23, 10/32, 12/10, 4/21. A rational number can also be written in the form of m/n , where n is not 0 and m & n are integers. For example: 15/7, -18/13, 3/-7, -6/-12. All Fractions can be termed as Rational Numbers, however, all Rational Numbers cannot be termed as Fractions. Only those Rational Numbers in which ‘m’ and ‘n’ are positive integers are termed as Fractions.

The increase in the percentage of the gases which prevent the escape of heat from the earth, which cause the average temperatures to increase worldwide is called greenhouse effect.

Heat is trapped by glass, and hence the temperature inside a glass enclosure will be much higher than the surroundings. This phenomenon was used to create an enclosure where tropical plants could be kept warm during the winters in colder climates. Such enclosures are called greenhouses. Carbon dioxide is one of the greenhouse gases.
