Answer 2

All are in proportion

Pls mark as brainliest

Explanation

(I) 20:30::40:60

Therefore if the product of 30 and 40 is equal to the product of 60 and 20 then they are in proportion

30x40=60x20

120=120

(ii) 8:9::16:18

8x18=9x16

144=144

Therefore they are in proportion

(iii) 2:3::6:8

2x8=6x3

18=18
