Adam has two bulbs of the following power ratings.

Bulb	Power rating
start text, A, end text	6, point, 0, space, start text, V, end text, slash, 18, space, start text, W, end text
start text, B, end text	6, point, 0, space, start text, V, end text, slash, 4, point, 0, space, start text, W, end text

He connects them in series across a 220, space, start text, V, end text battery, as shown.

What is the power dissipated by each bulb?

Power dissipated by bulb start text, A, end text, equals
Your answer should be
an integer, like 6
a simplified proper fraction, like 3, slash, 5
a simplified improper fraction, like 7, slash, 4
a mixed number, like 1, space, 3, slash, 4
an exact decimal, like 0, point, 75
a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, W, end text
