Question

4/9-1/4:5/6=? помогите пж

Answer 1

1) 1/4:5/6= 1/4*6/5= 3/10
2) 4/9-3/10= 40/90-27/90= 13/90

Answer 2

$\frac{4}{9} - \frac{1}{4} \div \frac{5}{6} = \frac{4}{9} - \frac{1}{4} \times \frac{6}{5} = \frac{4}{9} - \frac{1}{2} \times \frac{3}{5} = \frac{4}{9} - \frac{3}{10} = \frac{4 \times 10 - 3 \times 9}{9 \times 10} = \frac{40 - 27}{90} = \frac{13}{90}$
