Shift-click to select only the numbers. Hold the opt/alt key and the shift key and drag outward on a bounding box corner to resize the numbers. Holding the shift key constrains the resizing to the same proportions, and holding the opt/alt key allows the resizing to take place from the center. Next use the arrow keys to nudge them into position so you have something like this. If the guides get in your way, you can hide them at any time by going to View > Guides > Hide Guides.
