Question

Simplifique as frações abaixo, tornando-as irredutíveis:
a) 54/72
b) 96/120
c) 18/90
d) 81/108​

Answer 1

54 /72 (÷2/2)= 27/ 36 (÷3/3)= 9/12 (÷3/3)= 3/4

96/120(÷4/4)= 24/30 (÷2/2)= 12/15 (÷3/3)=4/5

18/90 (÷3/3)= 6/ 30(÷3/3) = 2/10(÷2/2)= 1/5

81/108= (÷3/3)= 27/36(÷3/3)= 9/12 (÷3/3)= 3/4

espero ter ajudado :)
