Question

a lifeguard received 15 hours of first aid training and 10 hours of cardiopulmonary resuscitation (cpr) training. What is the ratio of hours of CPR training to hours of first aid training

Answer 1

10/15 ten over 15 like a fraction you need to simplify that to 2/3 two over three

Answer 2

Answer: 2:3

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
`=(10)/(15)`

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

`(2)/(3)=2:3`

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