Question

Un mar jumate e un ban jumate 10 mere cat fac? E urgentttt

Answer 1

1[tex] 1\frac{1}{2} mere = 1 \frac{1}{2} bani \\ 10 mere = x bani\\ x= \frac{ 10*1\frac{1}{2}}{ 1\frac{1}{2}} \\ x= \frac{ 10\frac{3}{2}}{ \frac{3}{2}} \\ x= 5*3* \frac{2}{3} \\ x=5*2 \\ x=10 bani[/tex]

Answer 2

(1+ 1/2) mere ...... (1+1/2) bani
10 mere ..... x bani

Aplicăm regula de trei simplă.

1+1/2 = 3/2

x = (10•3/2)/(3/2)
= 10•(3/2)•(2/2)
= 10

=> 10 mere costă 10 bani.
