The whole unit ( numbers to the left of the decimal will remain as the degrees:
270 will remain as degrees
now multiply the decimal by 60:
0.50 * 60 = 30 ( this becomes the minutes) if the answer had a decimal, you would multiply that decimal by 60 for the seconds, but since multiplying 0.50 by 60 was a whole number there are zero seconds
so the answer becomes 270 degrees 30 minutes and 0 seconds
which is written like: 270°30'0"

To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation.
The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions. mber of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation. An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
Therefor we can conclude it is 2098 and we have made cheap and easy air travel.
