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

Respuesta :

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

[tex]\frac{N}{8.5}=\frac{6.3}{4.5}[/tex]

Solve for N:

[tex]N=\frac{6.3}{4.5}\times8.5=11.9[/tex]

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

The answer is: 11.9
