Question

Реши уравнение 9 целых 3/4:п=8 1/2-5целых 1/4.

Answer 1

$9 \frac{3}{4} \div n = 8 \frac{1}{2} - 5 \frac{1}{4} \\ 9 \frac{3}{4} \div n = 8 \frac{2}{4} - 5 \frac{1}{4} \\ 9 \frac{3}{4} \div n = 3 \frac{1}{4} \\ n = 3 \frac{1}{4} \ \div 9 \frac{3}{4}$

$\\ n = \frac{13}{4} \div \frac{39}{4} = \frac{13}{4} \times \frac{4}{39} = \frac{1}{1} \times \frac{1}{3} = \\ \frac{1}{3}$
