How will the force of the gravitational interaction between two bodies change if the mass of the first body is halved

How will the force of the gravitational interaction between two bodies change if the mass of the first body is halved and the mass of the second body is doubled?

F = G * m1 * m2 / R², where G is the gravitational constant, m1 is the mass of the first body, m2 is the mass of the second body, R is the distance between the bodies.
The force of attraction before changing the masses of bodies:
F1 = G * m1,1 * m2,1 / R1².
The force of attraction after changing the masses of bodies:
F2 = G * m1.2 * m2.2 / R2².
m1.2 = 0.5m1.1; m2,2 = 2m2,1
F2 / F1 = (G * m1.1 * m2.1 / R2²) / (G * m1.2 * m2.2 / R1²) = m1.1 * m2.1 / (0.5m1.1 * 2m2.1 ) = 1 / (0.5 * 2) = 1/1 = 1.
Answer: a) The force of gravitational interaction will not change.
