I am not sure how to go about solving this equation: 9.1-3.1 over the square root of 4 divided by 5. Do I start with the subtract?

Thank you very much for your help!  It is most appreciated and the equation finally made sense!

9.1-3.1=6

sqrt(4)=2, Then

6/2/5=3/5 which your answer.

Either $${\frac{\left({\mathtt{9.1}}{\mathtt{\,-\,}}{\mathtt{3.1}}\right)}{\left({\frac{{\sqrt{{\mathtt{4}}}}}{{\mathtt{5}}}}\right)}} = {\mathtt{15}}$$ or $${\frac{\left({\frac{\left({\mathtt{9.1}}{\mathtt{\,-\,}}{\mathtt{3.1}}\right)}{{\sqrt{{\mathtt{4}}}}}}\right)}{{\mathtt{5}}}} = {\frac{{\mathtt{3}}}{{\mathtt{5}}}} = {\mathtt{0.6}}$$. Depends on the context. Only one is right.
