Je voudrais la réponse de ces deux calculs s'il vous plait: 1) 5/8 + (-3/4) : (-9/16) 2) 6/5 - (-1/9) x (-3/4)

bonsoir

1) 5/8 + (-3/4) : (-9/16)

=5/8-3/4 x-16/9

=5/8+48/36

=5/8+(48÷12)/(36÷12)

=5/8+4/3

=(5*3)/(8*3)+(4*8)/(3*8)

=15/24+32/24

=47/24

2) 6/5 - (-1/9) x (-3/4)

=6/5+1/9 x -3/4

=6/5-3/36

=(6*36)/(5*36)-(3*5)/(36*5)

=216/180-15/180

=201/180

=(201÷3)/(180÷3)

=67/60
