21:00 in military or 24-hour time is 9:00 pm
Both 21 and 9 can be divided by 3. 21/3=7 9/3=3 So 21 over 9 can be simplified to 7 over 3.
3
7/3, 21 /3 = 7 9 /3 = 3
The greatest common factor (GCF) for 9 and 21 is 3.
21:00 in military or 24-hour time is 9:00 pm
The factors of 9 are: 1, 3, 9 The factors of 21 are: 1, 3, 7, 21
Both 21 and 9 can be divided by 3. 21/3=7 9/3=3 So 21 over 9 can be simplified to 7 over 3.
They are: 3*3 = 9 and 3*7 = 21
3*3 = 9 3*7 = 21
The GCF of 21 and 9 is 3. 21 and 9 can only be divided by three.
The factors of 9 are: 1, 3, 9 The factors of 21 are: 1, 3, 7, 21 The factors of 63 are: 1, 3, 7, 9, 21, 63
yes because 3 goes into 9 and 21. so 9/21 simplified is 3/7.
3
7/3, 21 /3 = 7 9 /3 = 3
The greatest common factor (GCF) for 9 and 21 is 3.
The GCF is 3.
