Respuesta :
10/15 ten over 15 like a fraction you need to simplify that to 2/3 two over three
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[tex]=\frac{10}{15}[/tex]
As 10 and 15 , both are the multiples of 5, thus divide both (numerator and denominator ) by 5, we get
[tex]\frac{2}{3}=2:3[/tex]
∴The ratio of hours of CPR training to hours of first aid training=2:3
