Find total instruments:
20+20+45+15 = 100
20 are brass
The portion would be number of brass over total:
20/100 which reduces to 1/5 are brass
Option 1. The equation that represents the direct variation that exists between a and b is b = –a.
<h3>How to find the direct variation here</h3>
The direct variation is of this form y ∝ x
This gives the equation
y = kx
The constant is k
From our question we have
b ∝ a so b = ka
b = 
a = 
Remember that b = ka
This would cancel out to
1 = -k
or k = -1
Hence the equation would be written as
b = -a
