1,75 x 40% :1/3 = 1 2/5 x 0,4 : 25% =.... Question from @csrafael

Takamori37 Atas:
$$\begin{align}1,75\times40\%:\frac13&=\frac{175}{100}\times\frac{40}{100}:\frac13 \\ &=\frac74\times\frac25:\frac13 \\ &=\frac74\times\frac25\times\frac31 \\ &=\frac{42}{20} \\ &=\frac{21}{10}=2\frac1{10}=2,1 \end{align}$

Bawah:
$$\begin{align}1\frac25\times0,4:25\%&=\frac{1(5)+2}{5}\times\frac4{10}:\frac{25}{100} \\ &=\frac75\times\frac25:\frac14 \\ &=\frac75\times\frac25\times\frac41 \\ &=\frac{56}{25}=2\frac6{25}=2,24\end{align}$

ImmanuelSinaga $$\begin{align}1)~~~1,75~\times~40\%~:~\frac{1}{3}~~&=~~\frac{7}{4}~\times~\frac{2}{5}~\times~\frac{3}{1} \\ &=~~\frac{7~\times~2~\times~3}{4~\times~5~\times~1} \\ &=~~\frac{42}{20} \\ &=~~\boxed{\bold{2\frac{1}{10}~~~atau~~~~2,1~~~atau~~~210\%}}\end{align}$

$$\begin{align} 1\frac{2}{5}~\times~0,4~:~25\%~~~&=~~\frac{7}{5}~\times~\frac{2}{5}~:~\frac{1}{4} \\ &=~~\frac{7}{5}~\times~\frac{2}{5}~\times~\frac{4}{1} \\ &=~~\frac{7~\times~2~\times~4}{5~\times~5~\times~1} \\ &=~~\frac{56}{25} \\ &=~~\boxed{\bold{2\frac{6}{25}~~~atau~~~2,24~~~atau~~~224\%}}\end{align}$
