Question

3 целых 5/12 умножить на 0,24

Answer 1

Решение:

$3 \dfrac{5}{12} \cdot 0,24 \ = \ \dfrac{3\cdot12+5}{12} \cdot \dfrac{24}{100}\ = \ \dfrac{41}{12} \cdot \dfrac{24}{100} \ = \ \dfrac{41\cdot24}{12\cdot100} \ = \ \dfrac{984^{:24}}{1200^{:24}} \ =$ $= \dfrac{41}{50} = 0,82$ 

$\displaystyle\mathtt{\boxed{\bold{OTBET: 0,82 } }}$
