Answer 1

Solve all to find wich one are equal:

a) 5:45 = 0.1111

b) 3:1.2= 2.5

c) 1.2:4 = 0.3

d) 0.2:3 = 0.066666

e) 6.3:21 = 0.3

f) 1:0.4 = 2.5

g) 1/3:3 = 0.1111

h) 3 1/3:50 = 0.0666

i) 20/9: 2/27 = 30

j) 1.5:0.05 = 30

So, by looking at the results :

a) and g)

b) f)

c) e)

i) j)

d)h)
