Question

виконайте дії: а)4/27•9/16; б)12/35:2/5; в)8 3/4:2 1/3; г)1 8/25•1 5/11; д)3 5/7•1 1/13; е)2 2/3•6.​

Answer 1

$\frac{4}{27} \times \frac{9}{16} = \frac{1}{12}$

$\frac{12}{35} \div \frac{2}{5} = \frac{12}{35} \times \frac{5}{2} = \frac{6}{7}$

$8 \frac{3}{4} \div 2 \frac{1}{3} = \frac{35}{4} \times \frac{3}{7 } = \frac{15}{4} = 3 \frac{3}{4}$

$1 \frac{8}{25} \times 1 \frac{5}{11} = \frac{33}{25} \times \frac{16}{11} = \frac{48}{25} = 1\frac{23}{25}$

$3 \frac{5}{7} \times 1 \frac{1}{13} = \frac{26}{7} \times \frac{14}{13} = 4$

$2 \frac{2}{3} \times 6 = \frac{8}{3} \times 6 = 16$
