63 and its multiples
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.
7/3, 21 /3 = 7 9 /3 = 3
1, 3, 7, 9, 21 and 63.
1, 3, 7, 9, 21, 63.
1, 3, 7, 9, 21, 63.
1, 3, 7, 9, 21, 63.
3*3 = 9 3*7 = 21
They are: 3*3 = 9 and 3*7 = 21
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
assuming question is 21/27 then 21/7 = 3 = 27/9 Answer: 7/9
3/7 = 9/21 (multiplying both the numerator and denominator by 3), therefore 3 over 7 is equal to 9 over 21.
