this the simplest form
1/7 + 1/3 = 3/21 + 7/21 = 10/21
1 over 3 7/21 = 1/3
3/7 = 9/21 (multiplying both the numerator and denominator by 3), therefore 3 over 7 is equal to 9 over 21.
7 over 3 or 21/3
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.
1/3 + 2/7 = 7/21 + 6/21 = 13/21
3/7 is bigger because 3/7 = 9/21 and 1/3 = 7/21
1 over 7 is the equivalent to 3 over 21.
1 over 21. 5/7 - 2/3 = 15/21 - 14/21 = 1/21
Yes, 21/3 = 7/1
3/21 = 1:7
3/21 = 1/7
