Dollhouse Handmade
Response to difficult math question?
Megan and Katie decided to sell bracelets made by hand. Katie can make three bracelets in four hours Megan and bracelets can make 4 to 5 hours. Working together, how long until they have made 31 bracelets? I came up with 40 hours … help! Also, Fia has her younger sister bought a dollhouse, and she and her father will hand paint it. By itself, Fia could paint in 6 hours. By itself, her father could painting in four hours. Working together, how long until this work is completed one? It took me two hours 10 minutes. Thanks! Thanks for the help! I'm in seventh grade so this is hard …
Problem 1) Katie 03/04 bracelet can make Megan an hour can make in 1 hour Bracelet 4.5 Together you can do: (3.4 + 4.5 = (3 * 5 + 4 * 4) / 4 * 5 = (15 +16) / 20 = 31/20) bracelets in 1 hour. that would take 20/31 hours to make a bracelet, leading to 31 * 20/31 = 20 hours to make 31 bracelets. o Problem 2) Fia could paint sixth house of dolls in one hour your father may 04/01 dollhouse in 1 hour Together they paint: (6.1 + 1.4 = (4 + 6) / 6 * 4 = 10/24) Doll House in 1 hour or that would take 24/10 = 2.4 hours = 2 hours 24 minutes to paint a doll's house
