40/6+5/6 x 2/3
= 40/6 + 10/18
= (40 x 3) / (6 x 3) + 10/18
= 120/18 + 10/18
= 130/18
= (2 x 65) / (2 x 3)
= 65/3
(5/6-40/6)diviser 2/3
= - 35/6 x 3/2
= - 105/12
= (3 x - 35) / (3 x 4)
= - 35/4
40/6+ 5/6(au carré) - 2/3´
= 40/6 + 5²/6² - 2/3
= (40 x 6) / (6 x 6) + 25/36 - (2 x 12) / (3 x 12)
= 240/36 + 25/36 - 24/36
= 241/36.
