Question

розважить ривняння 4/9х=3,6 4 2/7х=1

Answer 1

$\frac{4}{9} x = 3.6 \\ x = \frac{36}{10} \div \frac{4}{9} \\ x = \frac{36}{10} \times \frac{9}{4} \\ x = \frac{81}{10} \\ x = 8.1$

$4 \frac{2}{7} x = 1 \\ \frac{30}{7} x = 1 \\ x = 1 \div \frac{30}{7} \\ x = 1 \times \frac{7}{30} \\ x = \frac{7}{30}$
