Answer:
1.79487
Nearest tenth =1.8
Nearest hundredth = 1.79
Step-by-step explanation:
[tex]\frac{16\frac{2}{3} -15\frac{1}{6} +1.3}{2.5\cdot 1.56\cdot0.4}[/tex]
Convert mixed numbers to improper fractions
[tex]\frac{\frac{50}{3}-\frac{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\\\\=\frac{\frac{50}{3}-\frac{91}{6}+1.3}{1.56}\\\\\frac{50}{3}-\frac{91}{6}+1.3 = 1.3+\frac{3}{2}\\ \\=\frac{1.3+\frac{3}{2}}{1.56}\\\\\mathrm{Convert\:element\:to\:a\:decimal\:form}\\\\\frac{3}{2}=1.5\\\\=\frac{1.3+1.5}{1.56}\\\\=\frac{2.8}{1.56}\\\\\mathrm{Divide\:the\:numbers:}\:\frac{2.8}{1.56}=1.79487\dots[/tex]
