(5/7) of 21 = 21*5/7 = 3*5 = 15
5/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/21
5/21 + 1/7 = 56/147 or 8/21
7 over 10=7/10 and 5 over 21=5/217/10*5/21= 7*5/10*21= 35/210 which simplifies to: 1/6
3/5 * 7 = 21/5 = 41/5
1 over 21. 5/7 - 2/3 = 15/21 - 14/21 = 1/21
The answer is: 5/21 divided by 10/7 = 1/6
52/7 = 156/21 - 50/21 =106/21 or 5 and 1/21
5/7 x 7/10 = 35/70 = 1/2 1/2 x 5/21 = 5/42
5/8 + 7/5 = 21/40
Yes. 15/21 = 5/7. 5/7 is in simplest form.
21 / 35 = (7*3) / (7*5) = 3 / 5 ■
5/7 − 7/14 = 21/98 or 3/14
