Bună! ❤️
Ex 8.
O sticlă cu capacitatea de 3/4 litri = o sticlă cu capacitatea de 0,75 litri.
18 : 0,75 = /×100
1800 : 75 = 24 sticle
Ex 9.
[tex]67 \frac{1}{2} km = \frac{67 \times 2 + 1}{2} = \frac{135}{2} = 67.5km[/tex]
[tex]4 \frac{1}{2} ore = \frac{4 \times 2 + 1}{2} = \frac{9}{2} = 4.5ore[/tex]
[tex]v = \frac{d}{t} \\ \\ v = \frac{67.5km}{4.5h} = 15 \frac{km}{h} [/tex]
Succes ❗
