Question

(7/12 - 1/3) * 16/19 = ?
(11/24 - 1/6) * 1 3/5 = ?
(7 - 2 5/16) * 4/25 = ?

Answer 1

(7/12 - 1/3)* 16/19 = (7/12 - 4/12)*16/19 = 3/12 * 16/19 = 4/19

(11/24 - 1/6) * 1 3/5 = (11/24 - 4/24) * 8/3 = 7/24 * 8/3 = 7/9

(7 - 2 5/16 ) * 4/25 = (6 16/16 - 2 5/16) * 4/25 = 4 11/16  * 4/25 = 75/16 * 4/25 = 3/4
