1/4 * 28 = 7
1
2/7 + 1/4 (2*4)/(7*4) + 7/(4*7) 8/28 + 7/28 (8 + 7)/28 15/28
28 is the LCD
{1, 2, 4, 7, 14, 28} the opposite sides multiply to 28 (there are 6):(e.g., 2 * 14 = 28, 4 * 7 = 28)
28*1/7 = 4
1/4 * 4/7 = 4/28 = 1/7.

Yes, to 1/4 as 7 can go into itself once, and into 28 4 times.
17/4 x 27/7 = 459/28 or 16 and 11/28
28 * 6/7 = 4 * 6/1 = 24
24
1/4 * 28 = 7
7 / 8 x 4 / 14 7 x 4 = 28 8 x 14 = 112 28 / 112 same as 1 / 4
28
40/28 = 10/7 or 1 and 3/7
