Neporo4naja [7]

Answer: Ask the king to draw first and read it. Explain that if the king selects "leave" the PM's choice could only be "stay". It is then unnecessary for the PM to draw. It avoids embarrassing the king in his lie, demonstrates the PM's intelligence, and keeps his job.

2. The table shows the mass of fibres in 100 grams of each food item below. Food Mass of fibre (grams per 100 grams) Beans Bread

Andre45 [30]

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 <u>4.8 grams</u>.

<h3>How can the amount of fiber consumed be calculated?</h3>

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 = <u>4.8 grams</u>
