Sagot :
J = 18*(8/6 -5/6) = 18*3/6 = 54/6 = 9
K = 3/8*1/3 = 3/24
3/24 + 39/16 = 6/48+117/48 = 123/48 = 41/16
j) 18x4/3 - 18x5/6
= 24 - 15
= 9
k) 3/8x1/3 + 3/16x13
= 3/24 + 39/16
= 6/48 + 117/48 = 123/48
calcule les differente expression suivante de deux facons differentes en respectant les prioriter puis en utilisent la distributivite
j) 18*(4/3-5/6)
k) 3/8*1/3+3/16*13
J = 18*(8/6 -5/6) = 18*3/6 = 54/6 = 9
K = 3/8*1/3 = 3/24
3/24 + 39/16 = 6/48+117/48 = 123/48 = 41/16
j) 18x4/3 - 18x5/6
= 24 - 15
= 9
k) 3/8x1/3 + 3/16x13
= 3/24 + 39/16
= 6/48 + 117/48 = 123/48
