Iona buys a box of cereal. The cereal in the box weighs $$\(0.75 \mathrm{~kg}\)$$. Each helping of the cereal eaten by Iona has a weight of $$\(40 \mathrm{~g}\)$$. (a) Write $$\(40 \mathrm{~g}\)$$ as a fraction of $$\(0.75 \mathrm{~kg}\)$$. Give your answer in its simplest form. (2) The cereal in the box contains $$\(6.8 \mathrm{~g}\)$$ of protein for each $$\(100 \mathrm{~g}\)$$ of cereal. (b) Work out the amount of protein in each of Iona's helpings of cereal. (2) $$\(3 \mathrm{~g}\)$$ of every $$\(40 \mathrm{~g}\)$$ helping of cereal is fat. (c) Write $$\(3 \mathrm{~g}\)$$ as a percentage of $$\(40 \mathrm{~g}\)$$. $$\(\%\)$$ (2)
