Power consumed by a resistance

Problem

Two resistors R, start subscript, 1, end subscript, equals, 1, point, 2, space, \Omega and R, start subscript, 2, end subscript, equals, 1, point, 8, space, \Omega are connected as shown below.
The potential difference between the terminals is V, start subscript, start text, A, B, end text, end subscript, equals, 3, point, 6, space, start text, V, end text.
Find the ratio of power consumed by the resistors R, start subscript, 1, end subscript and R, start subscript, 2, end subscript.
