15 to 4
Multiply the 75 minutes by ( 1 hour/60 minutes) .Notice that any ratio you use during a conversion of units must be equal to ' 1 '.
It is: 20/120 = 1/6 in its simplest form
3/4 = 75%
25/75 = 1/3
15 to 4
It would take 10 hours for 75 percent of the radioactive substance to decay. This is because the half-life is 10 hours, so after one half-life 50 percent will decay, and after two half-lives 75 percent will decay.
Multiply the 75 minutes by ( 1 hour/60 minutes) .Notice that any ratio you use during a conversion of units must be equal to ' 1 '.
17 hours, 20 minutes at 75 mph
Reduced ratio of 100 to 75 is 4 to 3.
1L = 1000 mL Hence 750 mL : 1000 mL = 75 : 100 = 15 : 20 = 3: 4 Is the lowest ratio.
It is: 20/120 = 1/6 in its simplest form
9 hours 20 minutes.
3/4 = 75%
75% as a ratio would be 3:4 (for every 4 something 3 will have...)
20% of 75 = 20% * 75 = 0.2 * 75 = 15
It is: 36 to 240 which is 3 to 20 in its simplest form
