The country of Mathlandia still clings to its old-fashioned currency of pounds, shillings and pence. In fact,

4 pounds is equal to 3 shillings,

and 2 shillings is 1 pound and 10 pence.

How many pence is a shilling worth?

4 pounds = 3 shillings

4/3 pound = 1 shillings

2shillings= 1 pound and 10 pence

8/3 pounds = 1pound and 10 pence

5/3 pounds = 10pence

1pound = 3/5 * 10 pence = 6 pence

2shillings = 6pence+10pence = 16pence

1shilling = 8 pence

-------------

OR this way might be easier to understand:

3shillings = 4 pounds so

3/4 shilling = 1 pound

2shillings = 1pound and 10 pence so

2shillings - 10pence = 1 pound

so

3/4shillings = 2shillings - 10pence

10 pence = (2-0.75)shillings

10 pence = 1.25 shillings

(10/1.25)pence = 1 shilling

8pence = 1 shilling
