The factors of 21 are: 1, 3, 7, and 21. The factor pairs of 21 are (1, 21) and (3, 7).`1.3,7.21
3/21 + 7/21 = 10/21
The factors of 6 are 1, 2, 3, and 6. The factors of 21 are 1, 3, 7, and 21. The common factors of 6 and 21 are 1 and 3, and the GCF is 3.
It is: 21/63 = 1/3
The numbers that go into 21 evenly are 1, 3, 7, 21.
1/7 + 1/3 = 3/21 + 7/21 = 10/21
1 over 3 7/21 = 1/3
1 over 7 is the equivalent to 3 over 21.
1 over 21. 5/7 - 2/3 = 15/21 - 14/21 = 1/21
3/21 = 1/7
3/21 = 1:7
3/21 = 1/7
1/3 + 2/7 = 7/21 + 6/21 = 13/21
Yes it is 1 1/7. 24 = 21 + 3, so take it as (21 + 3)/21 = 21/21 + 3/21. So 21/21 =1 and 3/21 = 1/7.
3 over 7 x 21 over 1 and 21 over 1 x 3 over 7
28/1 ÷ 21/5 = 20/3 or 62/3
