I am trying check my daughter's work - she is struggling (and so am I!) I am pretty sure B is the answer, but I wanted a second opinion. Thank you!

Lara is making wreaths to sell at 4 craft shows. For each wreath, she uses the same number of blue flowers. She has 7 dozen blue flowers. Which shows the partial quotients that will help Lara find the greatest number of blue flowers she can use for each show? One dozen is 12 flowers.

A)The partial quotients are 3 and 4. the greatest number of flowers is 12
**B) The Partial quotients are 20 and 1. The greatest number of flowers is 21
C) The partial quotients are 4 and 7. The greatest number of flowers is 28.
D) The partial quotients are 4 and 12. The greatest number of flowers is 48.

I just want to let anyone who looked at this question and was curious - I was correct, the answer was B! :-)

84 flowers, 4 shows is 21 per show

B looks good
