\(\frac{864.48-432.96}{864.48.432}=\frac{432.2.48-432.2.48}{864.48.432}=\frac{0}{864.48.432}=0\)
\(A=\frac{864\cdot48-432\cdot96}{864\cdot48\cdot432}=\frac{432\cdot2\cdot84-432\cdot2\cdot48}{864\cdot48\cdot432}=\frac{0}{864\cdot48\cdot432}=0\)
\(\frac{864.48-432.96}{864.48.432}=\frac{432.2.48-432.96}{864.48.432}=\frac{432.96-432.96}{864.48.432}=0\)
a) \(100:17+53:17=\left(100+53\right):17=153:17=9\)
b) \(1895:5-1745:5=\left(1895-1745\right):5=150:5=30\)
c) \(\left(864.48-432.96\right):\left(864.48.432\right)\)
\(=\left(864.48-432.2.48\right):\left(864.48.432\right)\)
\(=\left(864.48-864.48\right):\left(864.48.432\right)\)
\(=0:\left(864.48.432\right)\)
\(=0\)
d) \(\left(16.17-5\right):\left(16.16+11\right)\)
\(=\left[16.\left(16+1\right)-5\right]:\left(16.16+11\right)\)
\(=\left[16.16+16-5\right]:\left(16.16+11\right)\)
\(=\left[16.16+11\right]:\left(16.16+11\right)\)
\(=1\)

y = 864 . 48 - 432.96 / 864.48.432
= 432 . 2 . 48 - 432 . 2 . 48 / 864 . 48 . 432
= 0 / 864 . 48 . 432
= 0
