Write the following number in figures:
four thousand and fifty four

Start by writing the number in a place value table.

ThousandsHundredsTensUnits
454

The number starts with 'four thousand' so the 4 will go into the 'thousands' column.

The number ends with 'fifty four' so a 5 will go in the 'tens' column and a 4 will go in the units column.

The number will therefore become 4054 in figures
