Bonjour


a)  -5 /3 +  -4/49  x  35 /12=      -5/3 + (-35/147)  = -5/3 - 5/21 = -35/21 -5/21 = -40/21

b) (7/8 -3) : 51/-7
= (7/8 -24/8) ; 51/-7
= -17/8 x -7/51 = 119/408 = 7/24
a) -5/3 + (-4/49) x 35/12
= -5/3 + (-140/588)
= -40/21 <== SIMPLIFIER

b) ( 7/8 - 3 ) : ( -51/2 ) = 
= -17/8 x ( -2/51 )
= 1/12
