4/x times 6/21 = 24/21x simplify (divide top and bottom by 3) = 8/7x
8 over 7x
4/7 * 1/6 = (4*1)/(7*6) = (2*1)/(7*3) = 2/21
29 divided by 6 equals 4
21/4 plus 3/4 = 6
Yes, it is. 6/21 =2/7 =4/14
2/3*6/7 = 12/21 = 4/7 in its lowest terms
7/24 * 6/21 = 1/12
6 over 4 is the same as 21 over 14 because if you set it up as a proportion and do 6*14 and 21*4 it would equal the same thing (which would be 84)
(4/7) / (6/11) = (4/7) * (11/6) = 44/42 = 22/21 or 11/21
4 x 6 - 3 = 21
There are several possible interpretations of the question:(6/7) / (8/21)6 / [7/(8/21)]6 / [(7/8)/21]et ceteraAssuming it is the first of these, (6/7) / (8/21) = (6/7) * (21/8) = (3/7) * (21/4)= (3/1) * (3/4) = 9/4 or 21/4
6/7 - 2/3 = 18/21 - 14/21 = 4/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
