To find the greatest common factor (GCF) of 63, 36, and 45, we need to determine the largest number that divides evenly into all three numbers. First, we find the factors of each number: 63 (1, 3, 7, 9, 21, 63), 36 (1, 2, 3, 4, 6, 9, 12, 18, 36), and 45 (1, 3, 5, 9, 15, 45). The GCF is the largest number that appears in all three lists, which is 9. Therefore, the greatest common factor of 63, 36, and 45 is 9.
The GCF of 35, 45 and 54 is just 1. There are no common factors between these 3 numbers aside from 1.
1, 3 and 9
1, 2, 3, 4, 6, 9, 12, 18, 36 1, 3, 5, 9, 15, 45
Since 36 is a factor of 72, all of its factors are included in the factors of 72.
To calculate the number of hours from 1:45 PM to 9:45 PM, first find the difference between the two times. From 1:45 PM to 9:45 PM is 8 hours. Therefore, there are 8 hours between 1:45 PM and 9:45 PM.
From 4:30pm to 6:15pm is 1 hour and 45 minutes.
From 7:45 AM to 2:20 PM is a total of 6 hours and 35 minutes. To break it down, there are 6 hours from 7:45 AM to 1:45 PM, and then an additional 35 minutes from 1:45 PM to 2:20 PM.
1 hour and 45 minutes before a specific time can be calculated by subtracting 1 hour and 45 minutes from that time. For example, if the current time is 3:00 PM, subtracting 1 hour would take you to 2:00 PM, and then subtracting 45 minutes would bring you to 1:15 PM. Therefore, 1 hour and 45 minutes before 3:00 PM is 1:15 PM.
11:45 am + 1 hr 40 min = 12:45 pm + 40 min = 1:25 pm.
1:45 pm
About 1 hour 36 minutes.
2 1/2 hrs
To calculate 12:15 PM plus 45 minutes, you first convert 12:15 PM to a 24-hour format, which is 12:15. Then, you add 45 minutes to get 12:15 + 45 minutes = 13:00, which is 1:00 PM in the 12-hour clock format. So, 12:15 PM plus 45 minutes is 1:00 PM.
1:45 am. 13:45 is 1:45 pm. C. 1:45 A.M
1 hour and 45 minutes.
1:45 PM to 3:18 PM is 1 hour and 38 minutes.
