Answer:

Proportion states that the two ratios or fraction are equal.

As per the given statement: For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts.

Let x be the ounces of cashew will a batch have.

then by definition of proportion, we have;

$\frac{3}{2} = \frac{60}{x}$

By cross multiply we have;

$3x = 120$

Divide by 3 on both sides we get;

$x = 40$

therefore, 40 ounces of cashews will a batch have for every 60 ounces of peanuts.
