Question

$2 \frac{1}{3} + 0,25+0,(5)=$

Answer 1

$\frac{2x3+1}{3}+\frac{25}{100}+\frac{5}{9}=\frac{7}{3}+\frac{1}{4}+\frac{5}{9}$. Amplifici la prima cu 12, la a doua cu 9 si la a treia cu 4. => (7*12)/(3*12) + (1*9)/(4*9) + 5*4/9*4 ==> 84/36 + 9/36 + 20/36 => (84+9+20)/36 = 113/36

Answer 2

(2x3+1)/3+25/100+5/9=
7/3+1/4+5/9=
12x7/36+9/36+20/36=
(84+9+20)/36=
113/36
