Question

Номер 597,598 помогите пожалуйста

Answer 1

номер 597

а

$12 times frac{1}{6} = 2 \ 2 times 1 frac{1}{2} = 2 times frac{2}{3} = frac{4}{3} = 1 frac{1}{3} \ frac{4}{3} times 3 frac{3}{4} = frac{4}{3} times frac{15}{4} = 5 \ 5 times 4 frac{1}{5} = 5 times frac{21}{5} = 21$

б

$3 times 5 frac{1}{4} = 3 times frac{21}{4} = frac{63}{4} = 15 frac{3}{4} \frac{63}{4} times1 frac{1}{7} = frac{63}{4} times frac{8}{7} = 18 \ 18 times 5 frac{1}{2} = 18 times frac{11}{2} = 99 \ 99 times times frac{4}{11} = 36$

номер 598

а

$( frac{2}{9} ) {}^{2} = ( frac{2 {}^{2} }{9 {}^{2} } ) = frac{4}{81}$

б

$( frac{2}{3} ) {}^{3} = frac{2 {}^{3} }{ {3}^{3} } = frac{8}{27}$

в

$( frac{1}{4}) {}^{3} = ( frac{ {1}^{3} }{ {4}^{3} } ) = frac{1}{64}$

г

$( frac{4}{3} ) {}^{3} = frac{4 {}^{3} }{3 {}^{3} } = frac{64}{27} = 2 frac{10}{27}$

д

$( frac{1}{5} ) {}^{3} = ( frac{ {1}^{3} }{ {5}^{3} } ) = frac{1}{125}$

е

$( frac{1}{3} ) {}^{2} = ( frac{ {1}^{2} }{ {3}^{2} } ) = frac{1}{9}$
