Answer:
Option C. His answer is not correct, because the same can not be less than either attend
Step-by-step explanation:
we have
[tex]\frac{12}{15}+\frac{1}{10} =\frac{13}{25}[/tex]
we know that
[tex]\frac{12}{15}=0.8[/tex]
[tex]\frac{1}{10}=0.10[/tex]
[tex]\frac{13}{25}=0.52[/tex]
substitute
[tex]0.80+0.10=0.52[/tex] ----> is not true
therefore
His answer is not correct, because the same can not be less than either attend
