Answer:
Below in bold.
Step-by-step explanation:
30 = 2 * 3 * 5
12 = 2 * 2 * 3
Note that 2 and 3 are common to both factors
so the HCF = 2*3 = 6.
Only one 2 and one 3 of the duplicates are included in the LCM:
so the LCM = 2 * 3 * 2 * 5 = 60
20 = 2 * 2 * 5
12 = 2 * 2 * 3
HCF = 2 *2 = 4
LCM = 2*2*3*5 = 60.

Answer: 7 hours 15 minutes, 6 hours 45 minutes, 5 hours 12 minutes, 6 hours 6 minutes
Step-by-step explanation:
7 1/4 hours = 7 hours + 1/4 × 60 = 7 hours 15 minutes
6 3/4 hours = 6 hours +3/4 × 60 = 6 hrs 45 mins.
5 1/5 hours = 5 hours + 1/5 × 60 = 5 hrs 12 mins.
6 1/10 hours = 6 hours + 1/10 × 60 = 6 hours 10 mins.
