\(\frac{864.48-432.69}{864.48.432}\)=  69

69 sai òi, mk vừa thi xog nè.huhu

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) \(\left(16.17-5\right):\left(16.16+11\right)\)

\(=\left[16.\left(16+1\right)-5\right]:\left(16.16+11\right)\)

\(=\left[16.16+16-5\right]:\left(16.16+11\right)\)

\(=\left[16.16+11\right]:\left(16.16+11\right)\)

\(=1\)

_Chúc bạn học tốt_

\(\frac{864.48-432.96}{864.48.432}=\frac{432.2.48-432.2.48}{864.48.432}=\frac{0}{864.48.432}=0\)

thankyou very much

Ta có cách giải như sau:

\(\frac{864.48-432.96}{864.48.432}\)= \(\frac{432.2.48-432.86}{864.48.432}\)=\(\frac{432.96-432.96}{864.48.432}\)=\(\frac{0}{864.48.432}\)=\(0\)

Have a nice night!everyone.

864.48-432.96/864.48.432

=432.96-432.96/864.48.432

=0/864.48.432

=0

Đề có sai không               

\(=\frac{432x2x48-432x96}{846x48x432}\)

\(=\frac{432x96-432x96}{846x48x432}\)

\(=\frac{0}{846x48x432}\)

\(=0\)

\(\frac{864\cdot48-432\cdot96}{864\cdot48\cdot432}\)

\(=\frac{432\cdot2\cdot48-432\cdot96}{864\cdot48\cdot432}\)

\(=\frac{432\cdot96-432\cdot96}{864\cdot48\cdot432}\)

\(=\frac{96\cdot\left(432-432\right)}{864\cdot48\cdot432}\)

\(=0\)
