Question

Amplificați prin 5 fracțiile​

Answer 1

Explicație pas cu pas:

$\frac{ {}^{5)} 4}{5} = \frac{20}{25} \\ \\ \frac{ {}^{5)} 9}{11} = \frac{45}{55} \\ \\ \frac{ {}^{5)} 10}{25} = \frac{50}{125} \\ \\ \frac{ {}^{5)} 60}{75} = \frac{300}{375}$

Answer 2

Salutare!:)

$formula \: \frac { {}^{m)} a}{ \: \: b} = \frac{a \times m}{b \times m} \\ \\ \frac{ {}^{5)} 4}{ \: \: \: 5} = \frac{4 \times 5}{5 \times 5} = \frac{20}{25} \\ \\ \frac{ {}^{5)} 9}{ \: \: 11} = \frac{9 \times 5}{11 \times 5} = \frac{45}{55} \\ \\ \frac{ {}^{5)} 10}{ \: \: 25} = \frac{10 \times 5}{25 \times 5} = \frac{50}{125} \\ \\ \frac{ {}^{5)} 60}{ \: \: 75} = \frac{60 \times 5}{75 \times 5} = \frac{300}{375}$
