Question

a jewelry maker uses 4/5 yards of wire to make 3 necklaces. She uses the same length of wire for each necklace. What length of wire will she use to make 5 of the same necklaces.

Answer 1

Answer:

$\frac{4}{3} \text \ yards\ of\ wire$

Step-by-step explanation:

She uses 4/5 yards of wire to make 3 necklaces

Then

In Oder to make 1 necklace she use :

$\frac{\left( \frac{4}{5} \right) }{3} =\frac{\frac{4}{5} }{\frac{3}{1} } =\frac{4}{5} \times \frac{1}{3} = \frac{4}{15}\ \ \small\text yards\ of \ wire$

Now to make to make 5 of the same necklaces she needs :

$\frac{4}{15} \times 5=\frac{4}{15} \times \frac{5}{1} =\frac{20}{15}= \frac{4}{3} \ \ \ \text \ yards\ of\ wire$
