+\textbf{Ratios} are used to show how much of one thing there is compared to
+another thing.
+
+Ratios will be written in two ways, either in words "2 to 1" or as "2:1". Both
+are read the same way.
+
+A question involving \textbf{ratios} will often ask you to find out how many of
+one thing there is.
+
+\subsection*{Worked Example}
+
+\begin{questions}
+
+\question
+
+20 sweets are shared between James and Sasha in the ration 1:3, how many sweets
+do James and Sasha each receive?
+
+The first step is to look at what the ratio means for each sweet that James
+gets, Sasha gets three so we can expect Sasha to have more sweets than James in
+our answer.
+
+The ratio 1:3 means that 4 parts are shared between the boys.
+
+To find out how many sweets are in 1 part, we divide 20 by 4.  $20 \div 4 = 5$
+sweets are in 1 part.
+
+Since James gets one part, we now know that he receives 5 sweets.
+
+Sasha gets 3 parts, so we times the number of sweets in 1 part by 3. $3 \times
+5 = 15$ sweets in 3 parts.
+
+Sasha gets 15 sweets.
+
+\textbf{Check}
+
+We can write this back in ration form as the number of sweets James has to
+Sasha is. 5:15 We know there has to be 20 sweets in total so we can check that
+we have shared all 20 sweets out by adding the numbers of sweets that James and
+Sasha have. $5 + 15 = 20$, so this supports our answer.

+\question
+
+John and Sam stand on a pair of scales, together the weigh 200kg, if the ratio
+of John and Sam's weights  is 2:3, how heavy is Sam?
+
+\begin{solution}[2in]
+
+Sum the sides of the ratio, to convert the ratio in to two fractions.
+
+$2 + 3 = 5$
+
+Therefore, Sam weighs $3 \div 5$'s of 200kg.
+
+Sam weighs 120kg.
+
+\end{solution}
+
+\question
+
+A recipe for a cake requires 200g of flour, 100g of butter, 50g of sugar and 2
+eggs.  The cake recipe indicates that the cake will serve 4. How much of each
+ingredient is necessary for the cake to serve 8?
+
+\begin{boxedminipage}{\linewidth}
+    Hint: What is the ratio of cake servings?
+\end{boxedminipage}
+
+\begin{solution}[2in]
+
+    Create a ratio between the people that the recipe serves (4) and the people to
+    serve (8).
+
+    4:8
+
+    Simplify the ratio.
+
+    1:2
+
+    So it takes 2 lots of each ingredient, for every 1 in the recipe.
+
+    This means:
+    \begin{itemize}
+        \item 400g of flour
+        \item 200g of butter
+        \item 100g of sugar
+        \item 4 eggs
+    \end{itemize}
+
+\end{solution}
+
+\question
+
+John and Sam run a race, in total the race takes them 1 hour, however John is
+twice as fast as Sam. How long does Sam take to finish the race?
+
+\begin{solution}[2in]
+
+    Create a ratio between John's time, and Sam's.
+
+    1:2
+
+    Therefore, Sam took twice (2 times) as long as John.
+
+    $2 \times 1hour = 2hours$
+
+\end{solution}
