(3/8*10/2-5/6):5/8
Va rog help me :)

Salut,

(3/8 × 10/2 - 5/6) ÷ 5/8 =

(30/16 - 5/6) ÷ 5/8 =

25/24 × 8/5 =

5/3

Răspuns:

Explicație pas cu pas:

( 3/8 × 10 / 2 - 5 / 6 ) : 5/8 =  5/3 = 1 intreg si 2 /3

= [ ( 3 × 5 ) / 8 - 5 / 6 ) : 5/ 8 =

= ( 15 / 8 - 5/6 ) : 5 / 8 =

    → cmmmc al numitorilor 8 si 6 = 24

= ( 45 / 24 - 20/24 ) × 8 / 5 =

= 25/24  ×  8 / 5 =

= ( 25 / 5 )× ( 8 / 24 ) =

= 5 × ( 1/3 ) =

= 5/3
