Answer 1

Explanation:

32:16=x:4

cross multiply

128:16x

x=8 kiwis

4:8=x:32 if in the first problem we see 8:4=32:16 then x=16 bulbs.

1:2=x:20

cross multiply

20=2x

x=10 bunch of seeded black grapes

3:2=x:22

cross multiply

66=2x

x=33 dollars

20:50=30:x

cross multiply

20x=150

x=7.5 meters of ribbon
