Question

Tính nhanh:

12 x 23 + 23 x 88 / 46 x 3 + 46 x 14

Answer 1

        \(\frac{12.23+23.88}{46.3+46.14}\)

\(=\frac{23.\left(12+88\right)}{46.\left(3+14\right)}\)

\(=\frac{23.100}{46.17}\)

\(=\frac{23.2.50}{23.2.17}\)

\(=\frac{50}{17}\)

Answer 2

\(\frac{12x23+23x88}{46x3+46x14}\)

=\(\frac{23x\left(12+88\right)}{46x\left(14+3\right)}\)

=\(\frac{23x100}{46x17}\)

= \(\frac{50}{17}\)

Answer 3

\(\frac{12\times23+23\times88}{46\times3+46\times14}\)

\(=\frac{23\times\left(12+88\right)}{46\times\left(14+3\right)}\)

\(=\frac{23\times100}{46\times17}=\frac{50}{17}\)
