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

Sagot :

WINNER123

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

MINIMOUSE

j) 18x4/3 - 18x5/6

= 24 - 15

= 9

 

k) 3/8x1/3 + 3/16x13

= 3/24 + 39/16

= 6/48 + 117/48 = 123/48
