Explicație pas cu pas:

$2.3 \times 4.1 = \frac{23}{10} \times \frac{41}{10} = \frac{23 \times 41}{100} = \frac{943}{100} = 9.43$

$1.7 \times 3.6 = \frac{17}{10} \times \frac{36}{10} = \frac{17 \times 36}{100} = \frac{612}{100} = 6.12$

$3.1 \times 4.3 = \frac{31}{10} \times \frac{43}{100} = \frac{1333}{100} = 13.33$

$4.2 \times 5.3 = \frac{42}{100} \times \frac{53}{100} = \frac{42 \times 53}{100} = \frac{2226}{100} = 2226$

$6.7 \times 1.1 = \frac{67}{10} \times \frac{11}{10} = \frac{737}{100} = 7.37$
