Hint 3 of 3
Cross out any flower that fails even one count; the one left standing is the answer.
Show solution
Approach: count petals and leaves on each flower and keep the one that matches both
- The ladybird's flower must have exactly 5 petals and exactly 3 leaves on its stem.
- Count the petals on each flower out loud and keep only the flowers that show 5 petals.
- Now count the leaves on those stems and keep only the one with 3 leaves.
- The flower that passes both counts is the one the ladybird sits on — choice B.
