If I have these values and need to calculate percentage, what are the significant figures I need?

1.23, 4.56

so 1.23/4.56 x 100 is 3 significant figures or 1? 
I just attached a similar question and used arbitrary values just to understand the significant figures pRt

Obse ved-ex pected Cxpected Laboratory Experiments 13 Accuracy and Precision Calculate the % difference for the your data versus the known accepted value of 1.18 g/cm for the density of acrylic (see formula above). Percent difference from accepted value for: 1.1१-1.18 1.18 0,847% 5.08% 0.424% Density by caliper/ruler measurement method: Density by water displacement method: 1-4-1.18 118 Density by neutral buoyancy method: For your individual experiment, the method with the smallest difference from the accepted value has the most accuracy. For your experiment, which method produces the best accuracy? Density by neutal buayancy methad Analysis of precision using group data (Optional) This section looks at precision for each of the three techniques by using data from the entire class. Your instructor will help compile a spreadsheet.
