$2,4\cdot\dfrac{2}{3}+\dfrac{2}{5}\div\dfrac{2}{5}=\dfrac{24}{10}\cdot\dfrac{2}{3}+\dfrac{2}{5}\cdot\dfrac{5}{2}=\dfrac{12}{5}\cdot\dfrac{2}{3}+1=\dfrac{4}{5}\cdot2+1=\dfrac{8}{5}+1=\dfrac{8}{5}+\dfrac{5}{5}=\\\\=\dfrac{13}{5}=2\dfrac{3}{5}$

Odpowiedź:

2*4 i 2/3= 2*14/3 = 28/3 = 9 i 1/3

2/5 : 2,5= 2/5 : 25/10= 2/5 *10/25( skracamy 5 i 10 przez 5)=2*2/25= 4/25

9 i 1/3 + 4/25= 9 i 25/75+ 12/75= 9 i 37/75
