Hi there!
This is very easy to do on a calculator.
Okay, so 112 ÷ 6 = 18.66666666667 (repeating decimal)
If you wanted to make a fraction it would be 56/3 - All you do is simplify the fraction down to it's lowest point, which in this case is 56/3. (You cut the numerator and denominator in half for this.)
Hope this helps!
