Question

Alexis has 32 2/5 ounces of beads. How many necklaces can she make if each uses 2 7/10 ounces of beads?

Answer 1

32 2/5 ÷ 2 7/10 let's turn above into improper fractions: 32 2/5 ----> 162/5 2 7/10 -----> 27/10 so, 162/5 ÷ 27/10 -------> 162/5 * 10/27 = 12 necklaces

Answer 2

12 necklaces

Explanation:

Given,

The total quantity of beads she has =
`32(2)/(5)` ounces,

Also, the quantity of beads needed for each necklace =
`2(7)/(10)` ounces,

Thus, the number of necklaces can be made

`=\frac{\text{total quantity of beads}}{\text{quantity of beads needed for each necklace}}`

`=(32(2)/(5))/(2(7)/(10))`

`=(162/5)/(27/10)`

`=(1620)/(135)`

`=12`
