Rose decided to create a flower bed n front of her house. One-half of her flower bed is planted with pink tukips. She plants three-fourths of the rest of the ground with purple irises. After that, she plants orange marigolds in one-half of what remains. the rest of the garden is planted with red gladiolas. What percent of her garden is planted in red gladiolas?

Question

I worked it out, and I get 12.5%
can someone tell me if that is correct?
If not, could you help me?
Thanks!
