I'mm not sure what you're asking but if you want to know what the actual size of the ant is just:
take 1.4 divided by 7 and that will give you the actual size: 0.2 cm
if you want to know how big the picture ant is just:
take 1.4 and multiply it by 7 then that will give you the actual size of the picture ant: 9.8 cm.
