Ajutorrrrr.... Ofer coroanaaaaa va roggg și ofer 40 puncte!

Prima punga
[tex]3 \frac{1}{2} = \frac{3 \times 1}{2} = \frac{3}{2} = 1.5 \: kg [/tex]

A doua punga
[tex]1.5 + 5\frac{3}{4} = \frac{5 \times 3}{4} = \frac{15}{4} = 1.5+ 3.75 = 5.25 \: kg[/tex]

Kg de mere in cele doua pungi
1,5+5,25=6.75 de kg (adica 6 kg si 75 de grame)

[tex] 3\frac{1}{2}  =\frac{7}{2}  = 3,5 [/tex]  kg ( mere in prima punga )

[tex] 5\frac{3}{4}  =\frac{23}{4}  = 5,75 [/tex]  kg

5,75 + 3,5 = 9,25 kg ( mere in a doua punga )

3,5 + 9,25 = 12,75 kg ( in total in cele doua pungi )

Succes❤
