Răspuns:
a. \(8 \times 9 > 6 \times 9\)
\(\Rightarrow 72 > 54\)
b. \(45:5 < 10:5 \times 2\)
\(\Rightarrow 9 < 2 \times 2\)
\(\Rightarrow 9 < 4\)
c. \(\frac{36}{3} = 3\)
Deci, casetele corect completate ar fi:
a. \(8 \times 9 > 6 \times 9\) \(12:2 > 12:6\)
b. \(45:5 < 10:5 \times 2\) \(10:2 > 10:5\)
c. \(\frac{36}{3} = 3\) \(36:2 = 2\)
