Помогите решить задание пожалуйста

$1.075 - 0.075 \times (2.65 - ( \frac{7}{48} - \frac{9}{80} ) \times 7.5) + 0.105 = 1$
1)

$( \frac{7}{48} - \frac{9}{80} ) \times 7.5 = \frac{7}{48} \times \frac{75}{10} - \frac{9}{80 } \times \frac{75}{10} = \frac{7 \times 15}{48 \times 2} - \frac{9 \times 15}{80 \times 2} = \frac{35}{32} - \frac{27}{32} = \frac{8}{32} = \frac{1}{4} = 0.25$

2)

$2.65 - 0.25 = 2.4$
3)

$0.075 \times 2.4 = 0.18$
4)

$1.075 - 0.18 = 0.895$
5)

$0.895 + 0.105 = 1$
