ok, so what this is is
mixed number is a+b where a is the whole number and b is the fraction
so
whole number times mixed number is
a(a+b)=aa+ab
that is what they measn with distribute
so if you did the top right one
2 and 1/3 imes 3=(2+1/3)(3)=(2)(3)+(1/3)(3)=6+1=7
if you did bottom middle
5 times 3 and 2/5=5(3+2/5)=(5)(3)+(5)(2/5)=15+10=25
