Answer 1

Step-by-step explanation:

a.

$\frac{81}{108 } = \frac{9}{12} = \frac{3}{4}$

3:4

b.1 km = 1000m

2km = 2000 m

1m = 100cm

2000×100

200000

$\frac{200000}{350} \\ = \frac{20000}{35} = \frac{4000}{7}$

4000:7

c.

$\frac{135}{80} = \frac{27}{16}$

27:16

d.

$\frac{3000}{750} = \frac{300}{75} = \frac{60}{15} = \frac{12}{3} = \frac{4}{1}$

4:1
