12/17 ÷ 4/21 = 63/17 or 312/17
That would be 21/4, or 5.25.
3/7 is.
21 over 4 is 5.25. 2.1 divided by 4 is 0.525.
22/77 ÷ 11/14 = 4/11
22
43/10 ÷ 21/5 = 121/22
(21/5) / (42/5) = (11/5) / (22/5) = (11/5) * (5/22) = 11/22 = 1/2
12/21 x 7/4 = 84/84 = 1
12/17 ÷ 4/21 = 63/17 or 312/17
That would be 21/4, or 5.25.
3/7 is.
