Baker made 5 pounds of icing. he used 4/9 of the icing to decorate. how much did he have left over?

If the baker made 5 pounds of icing and used 4/9 of the icing to make decorations, then he used:

5 * 4/9 =
= 20/9 =
= 2 2/9 [of icing]

To find out how much he has left over, we just need to substract 2 2/9 from 5:

5 - 2 2/9 =
= 3 - 2/9 =
= 2 7/9

The baker has 2 7/9 of the icing left.
