Question

Выполните действия: 1/3 * (2_2/15 * 6_1/4 - 5_1/3 * 1_1/8) + 4_5/9=?

Answer 1

$frac{1}{3} *( frac{32}{15}* frac{25}{4}- frac{16}{3}* frac{9}{8} )+ frac{41}{9} = frac{1}{3}* ( frac{8}{3}*5-2*3 )+ frac{41}{9} =$$frac{1}{3} * (frac{40}{3} -6)+ frac{41}{9} = frac{1}{3} * frac{22}{3} + frac{41}{9} = frac{22}{9} + frac{41}{9} = frac{63}{9} =7$
