12 one half times one nine
pshichka [43]

Answer:

1\frac{7}{18}  or one seven eighteenths

Step-by-step explanation:

we know that

12 one half times one nine is the same that multiply 12 one half by one nine

so

(12\frac{1}{2})(\frac{1}{9})

Convert mixed number to an improper fraction

12\frac{1}{2}=12+\frac{1}{2}=\frac{12*2+1}{2}=\frac{25}{2}

substitute

(\frac{25}{2})(\frac{1}{9})=\frac{25}{18}

Convert to mixed number

\frac{25}{18}=\frac{18}{18}+\frac{7}{18}=1\frac{7}{18}

therefore

12 one half times one nine is one seven eighteenths
