Answer:
6lbs
Step-by-step explanation:
Total # of Frankfurters needed.
[tex]19*2=38[/tex]
Divide the total needed by the amount in a lb, to find out how many lbs we need.
[tex]\frac{38}{7}=5.4[/tex]
Therefore, we need 6 full lbs in order to create at least 38 Frankfurters.
If we only have 5lbs, we can only create 35 Frankfurters.
5.4 pounds of frankfurters are needed for a picnic.
there are 7 frankfurters to the pound
let x pounds of frankfurters needed for a picnic. to supply 19 pupils with 2 frankfurters each.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
since there are 19 pupil and each of has 2 frankfurters.
total frankfurters = 19 x 2
= 38
required pound,
x =38/7
x = 5.4
Thus, 5.4 pounds of frankfurters are needed for a picnic to supply 19 pupils with 2 frankfurters each.
