bonjour
1 ) 8/3 * 1/4 = 8/12 = 2/3
2) 10/ 3 * 2/5 = 20/15 = 4/3
3 ) 8/7 x 1/2 = 8/14 = 4/7
4 ) 9/16 * 4/3 = 36/48 = 3/4
Hello,
1) 1/4 * 8/3 = (8 * 1)/(4 * 3) = 8/12 = 4/6 = 2/3
2) 2/5 * 10/3 = (2 * 10)/(5 * 3) = 20/15 = 4/3
3) 1/2 * 8/7 = (8 * 1)/(2 * 7) = 8/14 = 4/7
4) 4/3 * 9/16 = (4 * 9)/(16 * 3) = 36/48 = 18/24 = 9/12 = 3/4
