With the given ratio, Number of pork(lb) needed are [tex]\frac{18}{5}[/tex] lb.
"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."
We have
Ratio of beefs and pork for meat loaf = 5:2
Number of beef for meat loaf = 9 lb
Let number of pork be X
Ratio of beefs and pork for meat loaf
5 beef : 2 pork
9 beef : X pork
Number of pork needed
5X = 9 × 2
⇒5X = 15
⇒ X = [tex]\frac{18}{5}[/tex]
Thus, number of pork needed are [tex]\frac{18}{5}[/tex] lb.
