Question

Решите уравнение 31/76 + 45/76 - p = 15/31 и 13/58 + 21/58 - m = 6/29.

Answer 1

$frac{31}{76}+ frac{45}{76}-p= frac{15}{31} , \ frac{31+45}{76}-p= frac{15}{31} \ frac{76}{76}-p= frac{15}{31} \ 1-p= frac{15}{31}$
$p=1+ frac{15}{31} \ p=1 frac{15}{31}$

$frac{13}{58}+ frac{21}{58}-m= frac{6}{29} \ frac{13+21}{58}-m= frac{6}{29} \ frac{34}{58}-m= frac{6}{29} \ frac{17}{29}-m= frac{6}{29} \ m=frac{17}{29}-frac{6}{29} \m=frac{17-6}{29} \ m=frac{11}{29}$
