Sagot :
Bonsoir,
L= -7/5 / (2/9 - 7/18)
= -7/5 /( 4/18 -7/18)
= -7/5 /( -4/18
= -7/5 / (-2/9)
= -7/5 *-9/2
= 63/10
M= (4/5 + -3/2) / (-9/4 - 1/6)
= (8/10 - 15/10) / ( -27/12 - 2/12)
=( -7/10) / ( -29/12)
= 203/120
Bonsoir,
Calculer :
L = -7/5:(2/9-7/18)
L = -7/5:(-1/6)
L = 7/5:1/6
L = 7/5×6
L = 42/5
M = (4/5-3/2):(-9/4-1/6)
M = -7/10:(-9/4-1/6)
M = -7/10:(-29/12)
M = 7/10:29/12
M = 7/10×12/29
M = 7/5×6/29
M = 42/145
/ = fraction.
Bonne soirée.
