Question

Calcule a forma reduzida de cada fração a seguir: A)15/5 B)68/12 C)49/21

Answer 1

Explicação:

$\frac{15}{5} = \frac{5 \times 3}{5} = 3$

$\frac{68}{12} = \frac{34 \times 2}{6 \times 2} = \frac{34}{6} = \frac{17 \times 2}{3 \times 2} = \frac{17}{3}$

$\frac{49}{21} = \frac{7 \times 7}{3 \times 7} = \frac{7}{ 3}$

Answer 2

a)

$\color{blue}{\frac{15}{5}=3}\color{green}{\checkmark}$

b)

$\color{blue}{\frac{68\color{red}\div4}{12\color{red}{\div4}} =\frac{17}{3}}\color{green}{\checkmark}$

c)

$\color{blue}{\frac{49\color{red}\div7}{21\color{red}{\div7}} =\frac{7}{3}}\color{green}{\checkmark}$
