Question

Вычислите $1,6-\frac{1}{25}$

Answer 1

$\frac{8}{5} - \frac{1}{25} = \frac{5 \times 8}{25} - \frac{1}{25} = \frac{40}{25} - \frac{1}{25} = \frac{40 - 1}{25} = \frac{39}{25} = 1.56$

Answer 2

$1.6 - \frac{1}{25} = \frac{16}{10} - \frac{1}{25} = \frac{16 \times 5 - 1 \times 2}{50} = \frac{78}{50} = \frac{156}{100} = 1.56$
