4 pounds of fertilizer is mixed to make a mix of 80 pounds of soil.
<h3>What is Ratio ?</h3>
The relationship between two things is called Ratio. It is written in p:q form.
It is given that
For 10 pounds of soil , farmer mixes 8 ounces of fertilizer.
=8/16 = 0.5 pounds of fertiliser
The ratio is 10 : 0.5
Suppose he mixes x pounds of fertilizer for 80 pounds of soil
to determine x
The ratio is 80 : x
As they are in Proportion
10 / 0.5 = 80 /x
x = 80 * 0.5 /10
x = 4 pounds
Therefore 4 pounds of fertilizer is mixed to make a mix of 80 pounds of soil.
