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
Yes, 21/3 = 7/1
3/21 = 1/7
1/3 + 2/7 = 7/21 + 6/21 = 13/21
3 over 7 x 21 over 1 and 21 over 1 x 3 over 7
28/1 ÷ 21/5 = 20/3 or 62/3
21
6/7 + 1/3 You need to find the common denominator 18/21 + 7/21= 25/21= 1 and 4/21
24/21
3 over 21
3/21 = (3 x 1)/(3 x 7) = 1/7
no, 3/21 simplifies to 1/7
