### Step-by-step explanation:

${b}_{1}=\frac{13}{4}=\frac{13}{4}=3\frac{1}{4}=3.25$
${b}_{2}=\frac{78}{5}=\frac{78}{5}=15\frac{3}{5}=15.6$
${c}_{1}=\frac{36}{42}=\frac{6}{7}=0.8571$
${c}_{2}=\frac{27}{45}=\frac{3}{5}=0.6$
${d}_{1}=\frac{1}{2}-\frac{3}{5}+\frac{4}{7}=\frac{33}{70}=0.4714$
${d}_{3}=\left(\frac{4}{7}+\frac{1}{2}\right)\mathrm{/}5\frac{3}{7}=\frac{15}{76}=0.1974$ Did you find an error or inaccuracy? Feel free to write us. Thank you! Tips to related online calculators
