7/23.5/29+7/29.18/23-7/29
=(7.5)/(23.29)+7/29.18/23-7/29
=7/29.5/23+7/29.18/23-7/29.1
=7/29.(5/23+18/23-1)
=7/29.(1-1)
=7/29.0
=0
\(\frac{7}{23}\cdot\frac{5}{29}+\frac{7}{29}\cdot\frac{18}{23}-\frac{7}{29}\)
\(=\frac{7}{29}\cdot\frac{5}{23}+\frac{7}{29}\cdot\frac{18}{23}-\frac{7}{29}\)
\(=\frac{7}{29}\cdot\left(\frac{5}{23}+\frac{18}{23}-1\right)\)
\(=\frac{7}{29}\cdot0\)
\(=0\)

Ta có :\(37.\left(29-23\right)-29.\left(37-23\right)=37.29-37.23-29.37+29.23\)
\(=23.29-37.23\)
\(=23.\left(29-37\right)\)
\(=23.\left(-8\right)\)
\(=-184\)

37. (29 − 23) − 29.(37 − 23)
=[ 37.29 − 37.23 ] − [ 29.37 − 29.23 ]
=(37.29)-(37.23)-(29.37)+(29.23)
=(29.23)-(37.23)
=23(29-37)
=23.(-8)
=-184
37 . (29 - 23) - 29. (37 - 23)
= 37 . 29 - 37 . 23 - 29 . 37 - 29 . 23
= 37 . (29 - 29) - 23 . (37 - 29)
= 37 . 0 - 23 . 8
= 0 - 184
= 0 + (-184)
= -184
