Answer:

#color(purple)(2(1/4) rounds# or #color(purple)(2.25) rounds#

Explanation:

In 8 minutes -> 1 round

In 18 minutes -> (18/8) * 1 rounds

#=> 18/8 = (3 * 3 * cancel2) / (2 * 2 * cancel2) = 9/4 = 2 (1/4) rounds#

#=> 2 ((1* cancel(100)^25) / (cancel(4) * 100)) = 2 (25/100) = 2.25 rounds#

Answer:

2.25 rounds

Explanation:

This question can be easily solved by applying unitary method.

No. of rounds made by the clock in 8 minutes = #1#

No. of rounds made by the clock in 1 minute = #1/8#
No. of rounds made by the clock in 18 minutes = #1/8# x #18# = 2.25
