Question

5,1 : 8,7 = 34у/29 понятнее объясните плиз

Answer 1

Пошаговое решение:

$\frac{5.1}{8.7} = \frac{34y}{29}$

$\frac{5.1}{8.7} \times 8.7 = \frac{34y}{29} \times 8.7$

$5.1 \times 29 = \frac{34y \times 8.7}{29} \times 29$

$5.1 \times 29 = 34y \times 8.7$

$147.9 = 295.8y$

$295.8y = 147.9$

$295.8y \div 295.8 = 147.9 \div 295.8$

$y = 0.5$
