The difference of two rational numbers is -6/25 , if the greater number is -4/9 , what is trhe smaller number?
@ratu,
Hint: What is the lowest common denominator (actually any common denominator will do)?
x - (-4/9) = -6/25
x + 4/9 = -6/25
The lowest common denominator for 9 and 25 is 225.
x + 100/225 = -54/225
x = -54/225 - 100/225 = -154/225
