Question

27 calcule as expressões : a) 1/3*(3/5+1/2) b) 5/2*(4/3-3/4) c) (5/4-1/2)*(1/3+2/5)​

Answer 1

Resposta:

Explicação passo a passo:

1/3x(3/5+1/2)=

1/3x(6/10+5/10)=

1/3x11/10=

11/30

5/2x(4/3-3/4)=

5/2x(16/12-9/12)=

5/2x7/12=

35/36

(5/4-1/2)x(1/3+2/5)=

(5/4-2/4)x(5/15+6/15)=

3/4x11/15=

33/60
