Question

ВЫПОЛНИТЕ УМНОЖЕНИЕ:
0,8 × 7/12 ;
1/2/3 × 0,6 ;
1,25 × 32/45 ;
4,5 × 3/1/3 ;

Answer 1

$1)0.8 times frac{7}{12} \ \ frac{4}{5} times frac{7}{12} \ \ frac{1}{5} times frac{7}{3} = frac{1 times 7}{5 times 3} = frac{7}{15} \ \ 2)1 frac{2}{3} times 0.6 \ \ frac{2}{3} times frac{3}{5} = 2frac{1}{5} = frac{2}{5} . \ \ 3)1.25 times frac{32}{45} \ \ frac{5}{4} times frac{32}{45} = 5 frac{8}{45} = frac{8}{9} . \ \ 4)4.5 times 3frac{1}{3} \ \ frac{9}{2} times 3 frac{1}{3} = frac{9}{2} .$
