Question

Calculați1,(6):(3-3/5)0,5:3+1

Answer 1

Răspuns:

Explicație pas cu pas:

1,(6) = (16 - 1)/9 = 15/9 = 5/3

0,5 = 5/10 = 1/2

5/3 : (3 - 3/5)*1/2 : 3 + 1 = 5/3 : (15/5 - 3/5) * 1/2 : 3 + 1 = 5/3 : 12/5 *1/2 : 3 + 1

= 5/3*5/12 *1/2 : 3 + 1 = 25/36*1/2 : 3 + 1 = 25/72 : 3 + 1

= 25/72 *1/3 + 1 = 25/216 + 1 = 25/216 + 216/216 = 241/216
