Question

8 3/4 + 7 2/3 + 6 5/8 + 5 1/2​

Answer 1

Respuesta:

$\frac{685}{24}$

Explicación paso a paso:

$8\frac{3}{4}=\frac{8\cdot 4+3}{4}=\frac{35}{4}\\\\\\7\frac{2}{3}=\frac{7\cdot 3+2}{3}=\frac{23}{3}\\\\\\6\frac{5}{8}=\frac{6\cdot 8+5}{8}=\frac{53}{8}\\\\\\5\frac{1}{2}=\frac{5\cdot 2+1}{2}=\frac{11}{2}$

$\frac{35}{4}+\frac{23}{3}+\frac{53}{8}+\frac{11}{2}$

$mcm : 24$

$\frac{35}{4}+\frac{23}{3}+\frac{53}{8}+\frac{11}{2}=\frac{210}{24}+\frac{184}{24}+\frac{159}{24}+\frac{132}{24}=\frac{210+184+159+132}{24}=\frac{685}{24}$
