Answer: 2:3


Step-by-step explanation:

Given : Duration of first aid training received by lifeguard=15 hours.

Duration of cardiopulmonary resuscitation (CPR) training received by lifeguard=10 hours

Now, The ratio of hours of CPR training to hours of first aid training

=10:15\(=\frac{10}{15}\)

As 10 and 15 , both are the multiples of 5, thus divide both (numerator and denominator ) by 5, we get

\(\frac{2}{3}=2:3\)

∴The ratio of hours of CPR training to hours of first aid training=2:3
