5 divided by 1 / 3 means:
1 divided by (1 / 2 divided by 3 plus 1 / 3 divided by 5) means:
3 / 4 divided by (1 / 2 divided by 3 plus 1 / 3 divided by 5) means:
The numbers are as follows:
1 / 2 divided by 3 * 5 means:
5 divided by 1 / 3 means:
1 divided by (1 / 2 divided by 3 + 1 / 3 divided by 5) means:
3 / 4 divided by (1 / 2 divided by 3 + 1 / 3 divided by 5) means:
