Answer :

The answer is 10. As you do 25 * 2, divide this by 5.
First of all you must convert 25 into a fraction by putting it over one
[tex] \frac{25}{1} [/tex]×[tex] \frac{2}{5} [/tex].
Then you multiply accross [tex] \frac{25}{1} [/tex]×[tex] \frac{2}{5} [/tex]=[tex] \frac{50}{5} [/tex] then you divide the numerator(top) by the denominator(bottom) 
50÷5=10
You answer is 10
