3. Divide these amounts of money between Tony and Adam according to the ratio indicated. Tony’s share is the fi rst number in each of the ratios.


a) Share €24 in a ratio of 3 : 1 c) Share €56 in a ratio of 4 : 3 e) Share €48 in a ratio of 3 : 5


b) Share €30 in a ratio of 2 : 3 d) Share €27 in a ratio of 2 : 1 f) Share €72 in a ratio of 5 : 4


Gemma and Sinéad won a prize in a raffl e. They divided it between them so that Gemma got €40 and Sinéad got €24. What ratio did they divide the prize in?


If Gemma got €40 and Sinéad got €24, the total prize was €64. What fraction of the total prize did each get?


Gemma = 40


__ 64


__ 64 = 5


– 8


Sinéad = 24


__ 64


Now reduce the fractions to their lowest terms. 40


24


__ 64 = 3


– 8


The 2 numerators give you the ratio, so the prize was divided in a ratio of 5 : 3.


4. Work out what ratios were used to divide these prizes. Remember to add the 2 amounts to work out the total prize fi rst.


a) Joe got €16 and Jim got €8 b) Lorraine got €24 and Simon got €16 c) Phil got €30 and Paula got €50 d) Laura got €48 and Richard got €40
