Answer:
For number 10 it would be A [tex]20-7\frac{3}{4} -3\frac{1}{3} =\frac{107}{12}=8\frac{11}{12}[/tex]
For Number 11 it would be 7[tex]\frac{1}{7}[/tex], 7.25, 7.7
For 12 It would be [tex]\frac{3}{8}[/tex]
For 13 It would be
[tex]2\frac{3}{4}[/tex]
And for 14 it would be [tex]\frac{77}{25} = 3\frac{2}{25}[/tex]
