The question asks to find the fraction a/b that is equivalent to 7/20 and satisfies the condition a + b = 135. To solve this, we can set up two equations based on the information provided:
a/b = 7/20
a + b = 135
From the first equation, we can express a in terms of b as a = (7/20)b. Substituting this expression into the second equation gives us (7/20)b + b = 135. Simplifying this, we find (27/20)b = 135, leading to b = 100. Substituting b = 100 back into the equation a = (7/20)b gives us a = 35. Therefore, the fraction a/b is 35/100, which simplifies to 7/20, confirming its equivalence.
