Question

For every 6.3 lbs. of lettuce, othere are 4.5 lbs. of tomatoes. o If there are 8.5 lbs. of tomatoes, how many lbs. of lettuce are there? O

Answer 1

Let N be the amount of lbs of lettuce. The proportion 6.3:4.5 must be the same as N:8.5. Then:

`(N)/(8.5)=(6.3)/(4.5)`

Solve for N:

`N=(6.3)/(4.5)*8.5=11.9`

Then, if there are 8.5 lbs of tomatoes, there must be 11.9 lbs of lettuce.

The answer is: 11.9
