Answer: 8 batches Step-by-step explanation: To get the number of batches she made, we can just use proportion to solve it. But first, we need to convert 5 1/3 to improper fraction 5 1/3 = 16/3 Then we can now use the proportion to solve 2/3 cups = 1 batch 16/3 cups = x (note:5 1/3=16/3) cross multiply 2/3 × x = 16 /3 2x/ 3 = 16/3 we need to make x the subject of the formula, to do that we will multiply each side of the equation by 3/2 2/3 × 3/2 x = 16/3 × 3/2 6x /6 = 48 / 6 x = 8 Therefore she made 8 batches of cookies.
