Question

va rog am nevoie de ajutor e difficil​

Answer 1

$12-3\frac{24}{25} 11\frac{25}{25}-3\frac{24}{25} = 8+\frac{1}{25} =8\frac{1}{25}$

$1\frac{10}{11}\cdot \frac{7}{22}-\frac{5}{22} =\frac{21}{11}\cdot \frac{7}{22}-\frac{5}{22} =\frac{147}{242}-\frac{5}{22} =\frac{147}{242}-\frac{55}{242} =\frac{147-55}{242} =\frac{92}{242} =\frac{46}{121}$

Sper că te-am ajutat!

Succes!
