When the numerator and denominator of a fraction are each increased by 5, the

value of the fraction becomes 3/5

When the numerator and denominator of that same

fraction are each decreased by 5, the fraction is then 1/5

Find the original fraction.

(Hint: Let the fraction be p/q) Write in simultaneous equations

first equation:

(p+5)/(q+5) = 3/5 or

5p + 25 = 3q + 15

5p - 3q = -10

second equation:

(p-5)/(q-5) = 1/5 or

5p - 25 = q - 5

5p - q = 20

solve the two equations by adding them

The denominator of a rational number is greater than the numerator by 4. If the numerator is increased by 2 and the denominator is decreased by 1, the number becomes 7/8. Find the original rational number.
