Hey there!
Let's evaluate our keywords and translate these words into math so we can create an equation.
Our key word here is of. In mathematics, when we say of, we mean multiplication. For example, when we say, "1/2 of 10", it translates to 1/2 times 10, which equals 10/2 or 5.
Therefore, when we say 1/4 of the total washers (assuming w is the total amount of washers), we mean that 1/4 the total amount of washers represents how many have to be fixed. That would give us:
1/4(w) = 1/4w
As the problem says, the 6 washers that need to be replaced represent the total amount of washers that there are. That means that the 1/4w must equal 6 because that 6 is the amount that is broken.
Therefore, our answer is B.
Hope this helps!
