+7188 19 1/2=39/2
3 3/4= 15/4
(39/2)/(15/4) Let's flip 15/4 to 4/15 then multiply
(39/2)*(4/15) that's the new sentence
39*4=156
2*15=30
156/30=26/5
26/5=5 1/5
Just to check my work:
$${\frac{\left({\frac{{\mathtt{39}}}{{\mathtt{2}}}}\right)}{\left({\frac{{\mathtt{15}}}{{\mathtt{4}}}}\right)}} = {\frac{{\mathtt{26}}}{{\mathtt{5}}}} = {\mathtt{5.2}}$$
So I am correct and there you go!
