Question

141. 1) (9 2/3 - x): 3,5=17/35 : 1,02=?​

Answer 1

$(9 \frac{2}{3} - x) \div 3.5 = \frac{17}{35} \div 1.02$

$(9 \frac{2}{3} - x) \div 3.5 = \frac{17}{35} \div \frac{102}{100}$

$(9 \frac{2}{3} - x) \div 3.5 = \frac{17}{35} \times \frac{100}{102}$

$(9 \frac{2}{3} - x) \div 3.5 = \frac{10}{21}$

$9 \frac{2}{3} - x = \frac{10}{21} \times 3.5$

$9 \frac{2}{3} - x = \frac{10}{21} \times \frac{35}{10}$

$9 \frac{2}{3} - x = \frac{5}{3}$

$x = 9 \frac{2}{3} - \frac{5}{3}$

$x = 9 \frac{2}{3} - 1 \frac{2}{3}$

$x = 8$
