If you add five to the numerator and denominator of a minimalist fraction, you will get two fifths. What is the original minimalist fraction?
one-tenth
The sum of the numerator and denominator of a fraction is 130, which is about 11 out of 15
Let the denominator be x and the numerator be y. according to the meaning of the title, we can get: x + y = 130,11x = 15y. If the two formulas are combined, we can get x = 75 and y = 55, so the denominator is 75 and the numerator is 55
Generally do this type of problem is to use the unknown, find the relationship, the solution of the equation, very fast!
