Question

3supra4:1supra2 dupaia supra tot 4/3:8/2:5/9=

Answer 1

3/4:1/2 / 4/3 :8/2 :5/9=

=3/4 ·2/1 (simplificam 4 cu 2) / 4/3 ·2/8 · 9/5 (se simplifica: 4 cu 8; 3 cu 9; 2 cu 2))

=3/2: 3/5

=3/2 · 5/3 (se simplifica 3 cu 3)

=5/2

=4  1/2 (4 intregi si 1/2)

Answer 2

$\frac{ \frac{3}{4} \div \frac{1}{2} }{ \frac{4}{3} \div \frac{8}{2} \div \frac{5}{9} } = \frac{3}{4} \div \frac{1}{2} \times \frac{3}{4} \div \frac{2}{8} \div \frac{9}{5} = \frac{ \frac{3}{2} }{ \frac{4}{3} \times \frac{1}{4} \times \frac{9}{5} } = \frac{ \frac{3}{2} }{ \frac{36}{60} } = \frac{ \frac{3}{2} }{ \frac{3}{5} } = \frac{3}{2} \times \frac{5}{3} = \frac{5}{2} = 2.5$
