Eight cakes cost 4 pound who much do three cakes cost

8 cakes = £4

To find the cost of each cake, divide the number of cakes by the cost.

8/£4 = £2 per cake.

To find the cost of three cakes, multiply the cost per cake by three.

£2 x 3 = £6 

It cost £6 to buy three cakes.

1 cake cost .50 pounds
So 3 cakes are 1.50 pounds
