Question

Sue makes bracelets. She uses

8
1
4
inches of chain to make one bracelet. How many bracelets can she make from a chain that is
49
1
2
inches long?

Answer 1

6

Explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

(49 1/2)/(8 1/4) = (99/2)/(33/4)

= (99/2)(4/33) = (99/33)(4/2)

= (3)(2) = 6
