Tomika uses 6 1/9 inches of wire to make a necklace and 3 1/3 inches of wire to make a bracelet how many necklace and bracelet sets can she make if she uses 28 1/3 inches of wire in all?

Respuesta :

The answer is 3 necklaces and bracelets sets she can make

Solution:

Given that,

Length of wire used to make a necklace is:

[tex]6\frac{1}{9}\ inches = \frac{6 \times 9 + 1}{9} = \frac{55}{9}\ inches[/tex]

Length of wire used to make a bracelet is:

[tex]3\frac{1}{3}\ inches = \frac{10}{3}\ inches[/tex]

[tex]Their\ sum = \frac{55}{9} + \frac{10}{3}\\\\sum = \frac{55+30}{9} = \frac{85}{9}[/tex]

Given that she uses 28 1/3 inches of wire in all

[tex]28\frac{1}{3} = \frac{85}{3}\ inches[/tex]

[tex]Number\ of\ necklace\ and\ bracelet = \frac{\frac{85}{3}}{\frac{85}{9}}\\\\Number\ of\ necklace\ and\ bracelet = \frac{85}{3} \times \frac{9}{85} = 3[/tex]

The answer is 3 necklaces and bracelets sets she can make
