Sagot :
A = (1/3 + 5/6 ) / 3/2 = (2/6 +5/6) / 3/2 = 7/6 / 3/2 = 7/6 *2/3 = 14 / 18 = 7/9
ou
A = 1/3 + (5/6 / 3/2) = 1/3 + (5/6 * 2/3) = 1/3 +10/18 = 6/18 + 10/18 = 16/18 = 8/9
ou
A = 1/3 + (5/6 / 3/2) = 1/3 + (5/6 * 2/3) = 1/3 +10/18 = 6/18 + 10/18 = 16/18 = 8/9
1/3 + 5/6 : 3/2
= 1/3 + 5/6 x 2/3
= 1/3 + 10/18
= 6/18 + 10/18
= 16/18
= 8/9 <== SIMPLIFIER
