\(\frac{12.23+23.88}{46.3+46.14}\)
\(=\frac{23.\left(12+88\right)}{46.\left(3+14\right)}\)
\(=\frac{23.100}{46.17}\)
\(=\frac{23.2.50}{23.2.17}\)
\(=\frac{50}{17}\)
\(\frac{12x23+23x88}{46x3+46x14}\)
=\(\frac{23x\left(12+88\right)}{46x\left(14+3\right)}\)
=\(\frac{23x100}{46x17}\)
= \(\frac{50}{17}\)

\(3,54\times73+0,46\times25+3,54\times26+0,46\times75+3,54\)
\(=3,54\times\left(73+26+1\right)+0,46\times\left(25+75\right)\)
\(=3,54\times100+0,46\times100\)
\(=354+46=400\)

X x 2,5 + X x 7,5 = 46
X x ( 2,5 + 7,5 ) = 46
X x 10 = 46
X = 46 : 10
X = 4,6
x nhân ( 2,5+7,5) = 46
x nhân 10 = 46
x = 46 : 10 = 4,6

`34,64 xx 46 + 34,64 xx 53 + 34,64`
`=34,64 xx 46 + 34,64 xx 53 + 34,64 xx 1`
`= 34,64 xx (46 + 53 +1)`
`= 34,64 xx 100`

3,2 x x + 0,24 = 46
3,2 x x = 46 - 0,24
3,2 x x = 45,76
x = 45,76 : 3,2
x = 14,3
Vay x= 14,3
