Question

Найдите значение выражения: $6frac{3}{5} + 1frac{1}{9} * 0,72$

Answer 1

$6 frac{3}{5} + 1 frac{1}{9} times 0.72 = 7.4 \ 1 frac{1}{9} times frac{72}{100} = frac{10}{9} times frac{72}{100} = frac{8}{10} = frac{4}{5}$

$6 frac{3}{5} + frac{4}{5} = 6 frac{7}{5} = 7 frac{2}{5} = 7.4$

Answer 2

6_3/5 + 1_1/9 * 0,72 = 7,4

          2          1

1) 1_1/9 * 0,72 = 10/9 * 72/100 = (10* 72) / (9 * 100) = 8/10=0,8

2) 6_3/5 + 8/10 = 6_ 6/10 + 8/10 = 6_14/10 = 7_4/10 = 7,4 = 7_2/5
