Unless the display is the type that only contains a +1, it should have pinout like this:
Note that this datasheet illustration is a bit messed up and the bottom segment is D (not E), and next segment clockwise (lower left) is E. The 7447 pinout is here:
Simply wire the respective letters a..g together (through the 220R resistors). Pin 3 should go to +5 through a 1K resistor. Pin 5 should go to GND.
Note that this is an ancient display and an ancient TTL chip (both are museum old) and because it's TTL open inputs will read as 'high'. You need to tie them to appropriate logic levels (RBI should be '0' if you want to display a zero).
Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A..0x0F display odd segments here and there (below is from the 74LS47 which has the same logic).
