Question

alguem me ajuda rapidao
1/3 + 5/12 : 6/4

Answer 1

Divisão de frações conserva a primeira e multiplica pelo inverso da segunda.

3, 48|2

3, 24|2

3, 12|2

3, 6|2

3, 3|3

1, 1           2²*2²*3= 48

$\dfrac{1}{3} + \dfrac{5}{12}: \dfrac{6}{4}\\\\\\\\\\ \dfrac{1}{3}+ \dfrac{5}{12} \times \dfrac{4}{6}\\\\\\ \dfrac{1}{3}+ \dfrac{30}{48}\\\\\\\\ \dfrac{16}{48}+ \dfrac{30}{48}=\\\\\\\\ \dfrac{46}{48}= \boxed{\dfrac{23}{24}}$

Forte abraço!
