Answer:
a/b = 22/143
Step-by-step explanation:
Let a/b = 2/13; a = numerator; b = denominator
from a/b = 2/13; b=13a/2 ------ eq. 1
Lets define the equation from the problem
4(b-a) = a^2 ------ eq. 2
Substitute eq. 1 to eq. 2
4[(13a/2) - a] = a^2
Distribute 4 into the bracket
26a - 4a = a^2
22a = a^2 (simplify a)
22 = a (numerator)
substitute the value of a to eq. 1
b = 13(22) / 2
b = 143
Lets do the checking using the eq. 2
4(b - a) = a^2
4(143 - 22) = (22)^2
484 = 484
