Question

5/8:3/4=?
3 целых 1/9: 2 целых 11/12=?
6:8/15=?
​​

Answer 1

Ответ:

$\frac{5}{8} \div \frac{3}{4} = \frac{5}{8} \times \frac{4}{3} = \frac{5}{6}$

$3 \frac{1}{9} \div 2 \frac{11}{12} = \frac{28}{9} \div \frac{35}{12} = \frac{28}{9} \times \frac{12}{35} = \frac{112}{105} = 1 \frac{7}{105}$

$6 \div \frac{8}{15} = \frac{6}{1} \div \frac{8}{15} = \frac{6}{1} \times \frac{15}{8} = \frac{45}{4} = 11 \frac{1}{4} = 11.25$
