Question

выполните действия (3,8 • 1,75 : 0,95 - 1,02) : 2,3 + 0,4

Answer 1

$( frac{38}{10} times frac{175}{100} div frac{95}{100} - frac{102}{100} ) div frac{23}{10} + frac{4}{10} = ( frac{38 times 175 times 100}{10 times 100 times 95} - frac{102}{100} ) times frac{10}{23} + frac{4}{10} = (7 - 1.02) times frac{10}{23} + frac{4}{10} = frac{598 times 10}{100 times 23} + frac{4}{10} = frac{26}{10} + frac{4}{10} = frac{30}{10} = 3$
