Mixed fractions are a curse on humanity and likely only, barely, suitable for everything positive domains. Four and one third is straightforward enough (curse on humanity aside), but ... even that "legal" Test 2: of negative four and one third is sketchy. Are we all happy with negative thirteen thirds, or are there some out there screaming into a pillow FFS, NO, it's negative eleven thirds ? It's alright to be super confused, the harder mixed fractions are looked at, the more poorly formed they seem.
