Mathematics Competition

Mathematics Faculty Competition:
This competition is open to ALL students at WCCS (staff and parents are welcome to have a go as well and will receive certificates but not the final prize).
To win the $30 prize you need to:

Find a three-digit number which gets 7 times smaller after its middle digit is deleted.

Entries should be submitted to Mr R Jackson by the 23rd of June (Monday of week 9). The winning entry will show clear working showing each logical step needed to find the three-digit number. The solution will be published in a newsletter after the competition ends. Please write your entry on a separate piece of paper clearly labelled with your name and mathematics class.
