Question 1036238

In geometry, if the sum of the angles is 180O, the two are called supplementary angles. Find the measurement of two supplementary angles is their difference is 54O.	

The denominator of a fraction is one more than the numerator. If the numerator is decreased by 1 and the denominator is increased by 2, the resulting fraction is ½. Find the original fraction.
