Question

5 2/7 + ( -3/4) ? Пожалуйста срочно

Answer 1

=5 8/28-21/28=4 15/28

Answer 2

$5 \frac{2}{7} + ( -\frac{3}{4})=$

$\frac{37}{7} + (- \frac{3}{4}) =$

$\frac{37}{7} - \frac{3}{4} =$

$\frac{148^|^4}{28} - \frac{21^|^7}{28} = \frac{148}{28} - \frac{21}{28} =$

$\frac{148}{28} - \frac{21}{28} = \frac{127}{28}$ = $\frac{15}{28}$




$OTBET: \frac{127}{28}$ = $4 \frac{15}{28}$
