Learning Intention Explain how to work out proportional division by using shares. Ratio & Proportion Proportional Division

Ratio & Proportion Example :Bill and Ben share a raffle win of £400 in the ratio 3:5. How much does each get ? Proportional Division Step 1 :Since the ratio is 3:5, there are : 3+5 = 8 shares Step 2 :Each share is worth : Step 3 :Bill gets 3 x 50 = £150 Ben gets 5 x 50 = £250 Check ! =

Ratio & Proportion Example :Ryan and Ross share 24 cakes in the ratio 3:1. How many cakes does each get ? Proportional Division Step 1 :Since the ratio is 3:1, there are : 3+1 = 4 shares Step 2 :Each share is worth : Step 3 :Ryan gets 3 x 6 = 18 Ross gets 1 x 6 = 6 Check ! =
