Klio2033 [76]

Answer:

4 bottles

Step-by-step explanation:

Given

Fertilizer = \frac{1}{2}L

Bottles = \frac{1}{8}L

Required

Determine the number of bottles

Represent the number of bottles with N

<em>This implies that N bottles of </em>\frac{1}{8}L<em> fit into </em>\frac{1}{2}L<em> of fertilizer. The relationship between them is:</em>

<em></em>Fertilizer =  Bottles * N

\frac{1}{2}L = \frac{1}{8}L* N

\frac{1}{2} = \frac{1}{8}* N

Multiply through by 8

8 * \frac{1}{2} = 8 * \frac{1}{8}* N

4 = 1* N

4 = N

N = 4

<em>Hence, there are  N = 4</em>
