How do you do 1/3 times 15 times 4

$${\frac{{\mathtt{1}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{4}} = {\mathtt{20}}$$

or

$${\frac{\left({\mathtt{1}}{\mathtt{\,\times\,}}{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{4}}\right)}{{\mathtt{3}}}} = {\mathtt{20}}$$

15= 15/1, 4= 4/1 and 1/= 1/3 1/3 * 15/1= 5/1= 5 4/1= 4 5*4=20

The anwser is 20

What's easy for me is to turn the fraction into a decimal because I'm not a big fan of fractions. After you turn it into a decimal, then you just multiply it all together. You should get 20.
