Explanation:

`(16(2)/(3) -15(1)/(6) +1.3)/(2.5\cdot 1.56\cdot0.4)`

Convert mixed numbers to improper fractions

`((50)/(3)-(91)/(6)+1.3)/(2.5\cdot \:1.56\cdot \:0.4)\\\\\mathrm{Multiply\:the\:numbers:}\:2.5\cdot \:1.56\cdot \:0.4=1.56\\\\=((50)/(3)-(91)/(6)+1.3)/(1.56)\\\\(50)/(3)-(91)/(6)+1.3 = 1.3+(3)/(2)\\ \\=(1.3+(3)/(2))/(1.56)\\\\\mathrm{Convert\:element\:to\:a\:decimal\:form}\\\\(3)/(2)=1.5\\\\=(1.3+1.5)/(1.56)\\\\=(2.8)/(1.56)\\\\\mathrm{Divide\:the\:numbers:}\:(2.8)/(1.56)=1.79487\dots`
