Answer 1

Respuesta:

$=1\frac{23}{28}$

Explicación paso a paso:

$3\:1/4-\:2\:1/2:\:1\:3/4\\\\3\frac{1}{4}-2\frac{1}{2}\div \:1\frac{3}{4}\\\\=\frac{13}{4}-2\frac{1}{2}\div \:1\frac{3}{4}\\\\=\frac{13}{4}-\frac{5}{2}\div \:1\frac{3}{4}\\\\=\frac{13}{4}-\frac{5}{2}\div \frac{7}{4}\\\\=\frac{13}{4}-\frac{5}{2}\times \frac{4}{7}\\\\=\frac{13}{4}-\frac{10}{7}\\\\=\frac{91}{28}-\frac{40}{28}\\\\=\frac{91-40}{28}\\\\=\frac{51}{28}\\\\=1\frac{23}{28}$
