calculati a 7×3/5,b 2×5/8,c 1/3×12, d


Răspuns :

a) 7×3/5 = 21/5

b) 2×5/8 = 10/8⁽² = 5/4

c) 1/3×12 = 12/3 = 4

[tex]a)7 \times \frac{3}{5 } = \frac{21}{5} [/tex]
[tex]b)2 \times \frac{5}{8} = \frac{10}{8}[/tex]
simplificam fractia cu 2
[tex] = \frac{5}{4} [/tex]
c) [tex] \frac{1}{3} \times 12 = \frac{12}{3} = 4[/tex]
