As a hint, if something contains 2.5% by weight, that means it contains 2.5 grams per 100 grams of material. So how much total fibre does 100 g of frozen oven chips contain. How much for 150 g?

What does 2.5% mean to you?

It should mean that:

In 100 grams portion, there are 2.5 grams of fiber.

In 200 grams portion, there are (2.5*2 = ) 5 grams of fiber.

In 150 grams portion, there are (2.5*1.5 = ) ? grams of fiber.
