A = 5/6 - 1/3 * 7/2 + 11/6
A = 5/6 - [(1 * 7)/(3 * 2)] + 11/6
A = 5/6 - 7/6 + 11/6
A = 9/6
A = (3 * 3)/(2 * 3)
A = 3/2
B = 4/5 * 2/7 * 9/10
B = [(4 * 2 * 9)/(5 * 7 * 10)]
B = 72/350
B = (2 * 36)/(2 * 175)
B = 36/175
Bonjour;
A=
5/6 -7*6 +11/6
= -2/6 +11/6
= -9/6 = -3/2
B=
8/35 *9/10
= 72/350
= 36/175
