12 : 12 : 6
30 = (12x2) + (6x1)
so ratio will be
12 : 12 : 6 = 2 : 2 : 1
If you change them both into seconds, you get a ratio of 60:2, but if you cancel it down you get an answer of 30:1 This means that the best answer is 30:1
It is: 1 to 2 in its simplest form
The ratio of 30 to 10 is the same as a ratio of 3 to 1.
1/4
It is: 10 to 20
30 to 2 = 15 to 1
It is: 1 to 2
If you change them both into seconds, you get a ratio of 60:2, but if you cancel it down you get an answer of 30:1 This means that the best answer is 30:1
30 minutes = 1/2 hour(30 minutes)/(1 hour) = 1/2
2:1
It is: 1 to 2 in its simplest form
The ratio of 30 to 10 is the same as a ratio of 3 to 1.
30 compressions to 2 breaths for one rescuer and 15 compressions to 2 breaths for 2 rescuers (also use the two hands encircling thumbs position for 2 rescuers). The old compression ratio was 5 compressions to 1 breath.
52 to 2 i think i had it on a test once
1/4
It is: 10 to 20
In its simplest form... 1:30 seconds
