Answer 1

Răspuns:

5

Explicație pas cu pas:

$3 \dfrac{2}{3} \times 2 \dfrac{1}{37} - 2 \dfrac{1}{37} \times 1.2 =$

$= \dfrac{9 + 2}{3} \times \dfrac{74 + 1}{37} - \dfrac{74 + 1}{37} \times \dfrac{12}{10}$

$= \dfrac{11}{3} \cdot \dfrac{75}{37} - \dfrac{75}{37} \cdot \dfrac{12}{10} = \dfrac{75}{37} \cdot \bigg(\dfrac{11}{3} - \dfrac{12}{10} \bigg)$

$= \dfrac{75}{37} \cdot \dfrac{55 - 18}{15} = \dfrac{75}{37} \cdot \dfrac{37}{15} = \bf 5$
