A small tin of beans contains 200 grams. If you are going to eat two-thirds (2/3) of this small tin of beans, how much fibres will you consume? Show your calculations. (2 marks)​

Answer 1

Given that the amount of fiber in 100 grams of beans is 3.6 grams the amount of fiber consumed from  $\mathbf{\frac{2}{3}}$ of the small tin is 4.8 grams.

How can the amount of fiber consumed be calculated?

From the given table, we have;

Mass of fiber in 100 g of beans = 3.6 grams

Mass of beans in the small tin = 200 grams

The quantity of the beans eaten = $\frac{2}{3}$ of the small tin

Required:

The amount of fiber to consumed from eating  $\frac{2}{3}$ of the small tin

Solution;

$Amount \ of \ fiber \ consumed = 200 \, g \times \dfrac{3.6 \, g}{100 \, g} \times \dfrac{2}{3} = \mathbf{4.8 \, g}$

Therefore;

The amount of fiber consumed by eating $\frac{2}{3}$ of the small tin = 4.8 grams
