5/12 × 4 = 5*4/12 = 20/12 = 1 8/12 = 1 2/3
3/7 * 49 = 3*49/7 = 3*7 = 21
5/8 : 25 = 5/(8*25) = 1/(8*5) = 1/40 = 0,025
3 1/6 : 19/24 = 19/6 * 24/19 = 24/6 = 4
3 3/7 * 1 1/6 = 24/7 *7/6 = 24/6 = 4
3/7 * 49 = 3*49/7 = 3*7 = 21
5/8 : 25 = 5/(8*25) = 1/(8*5) = 1/40 = 0,025
3 1/6 : 19/24 = 19/6 * 24/19 = 24/6 = 4
3 3/7 * 1 1/6 = 24/7 *7/6 = 24/6 = 4
