Bethany from Tattingstone, Douglas from Burgoyne Middle School and Amelia who goes to Norland Place School all decided the answer to this problem was the number 1. Douglas said:

First I worked out which things seemed to make a good choice to start looking at. Multiplying by 1 seemed to be a good idea, although I found that this didn't make any whole numbers so I scrapped it.
Then I tried multiplying by two. The best answer I found was three (51/34x2).
Finally I tried multiplying by four. I found the best answer, it was one (13/52x4).
I didn't try five because I knew it wouldn't make less than one.This means the answer is 13/52x4.

Amelia told us:

Think of a big number to divide by. Try something ending in 4 as it will be divisible by 2.
After lots of experimenting I came up with 51x2/34=3.
I also came up with 52/13x4 but my teacher explained that this would only equal 1 if I could put brackets
around (13x4) or else it would be actually equal to 16.

Bethany used a calculator to move the numbers around and try different combinations. She arrived at 13x4/52.

Fantastic! Three different solutions to admire.
