Question

Katie is having fun measuring things. This is what she discovered:
2 straws are as long as 5 crayons. 15 crayons are as long as 28 paperclips.
How many paperclips are as long as 3 straws?

Answer 1

s = long of straws

c = long of crayons

p = long of paperclips

2 straws are as long as 5 crayons means:

2 s = 5 c

5 c = 2 s

5 crayons are as long as 28 paperclips means:

5 c = 28 p

Since: 5 c = 2 s

2 s = 28 p

Multiply both sides by 1.5

3 s = 42
