Cevap

Since the ratio of potatoes to soldiers is constant, and the number of soldiers increases by a scale factor of

4

(from

15

60

), the pounds of potatoes must also be multiplied by

4

(

4 \times 4 = 16

Adım Adım Çözüm

Set up a proportion matching pounds of potatoes to the number of soldiers.

\frac{4}{15} = \frac{x}{60}

This proportion relates the known ratio (

4

pounds for

15

soldiers) to the unknown quantity

x

for

60

soldiers.

Solve for the unknown quantity

x

x = \frac{4 \times 60}{15} = 4 \times 4 = 16

Solving the equation gives the total pounds of potatoes needed to maintain the same ratio.
