Question

помогите пожалуйста ​

Answer 1

1)

$(x - 5 \frac{7}{12} ) \div 25 = \frac{7}{25} \\ (x - \frac{132}{25} ) \times \frac{1}{25} = \frac{7}{25} \\ \frac{25x - 132}{625} = \frac{7}{25} \\ 25x - 132 = 175 \\ 25x = 175 + 132 \\ 25x = 307 \\ x = \frac{307}{25} \\ x = 12.28$

2)

$18 - 2x = 16 \frac{3}{4} \\ 18 - 2x = \frac{67}{4} \\ - 2x = \frac{67}{4} - 18 \\ - 2x = - \frac{5}{4} \\ x = \frac{5}{8} \\ x = 0.625$
