Answer 1

Răspuns:

i)

$6 \frac{12}{35}$

j)

$\frac{8}{75}$

Explicație pas cu pas:

i)

$2 \frac{1}{10} + 3 \frac{1}{35} + 1 \frac{3}{14}$

$(2 + 3 + 1) + ( \frac{1}{10} + \frac{1}{35} + \frac{3}{14} )$

$6 + ( \frac{1}{10} + \frac{1}{35} + \frac{3}{14} ) = 6 + \frac{12}{35}$

$6 \frac{12}{35}$

j)

$\frac{7}{120} + \frac{11}{240} + \frac{1}{400}$

$\frac{70 + 55 + 3}{1200}$

$\frac{128}{1200}$

Simplifica fracția cu 16

$\frac{8}{75}$

Succes!
