Answer 1

She spent 7/10 of her money on a book and 10/100 of her money in food.

The money she spent altogether will be the sum of 7/10 and 10/100:

$\begin{gathered} M=\frac{7}{10}+\frac{10}{100} \\ M=\frac{7}{10}+\frac{1}{10} \\ M=\frac{8}{10} \\ M=\frac{4}{5} \end{gathered}$

Answer: she spent 4/5 of her money.
