Question

1- Simplifique as frações até chegar a uma fração irredutível.a) 21/28b)16/32c)16/25d)10/6E)9/45F)15/45

Answer 1

A) 3/4
B) 1/2
C) 16/25 Mesmo
D) 5/3
E) 1/5
F) 1/3

Answer 2

vamos lá...

$a)~~ \frac{21:7}{28:7} = \frac{3}{4} \\ \\ b)~~ \frac{16:2}{32:2} = \frac{8:8}{16:8} = \frac{1}{2} \\ \\ c)~~ \frac{16}{25} = \frac{16}{25} \\ \\ d)~~ \frac{10:2}{6:2} = \frac{5}{3} \\ \\ e)~~ \frac{9:3}{45:3} = \frac{3:3}{15:3} = \frac{1}{5} \\ \\ f)~~ \frac{15:5}{45:5} = \frac{3:3}{9:3} = \frac{1}{3}$
