a) (4 + 32 + 6) + (10 – 32 – 2)
b) 300:4 + 300:6 – 25
c) 17.[29 – (-111)] + 29.(-17)
d) 19.43 + (-20).43 – (-40)
\(a,\left(4+32+6\right)+\left(10-32-2\right)\\ =\left(10+32\right)+\left(10-32-2\right)\\ =10+32+10-32-2\\ =20-2\\ =18\\ b,300:4+300:6-25\\ =300:\left(4+6\right)-25\\ =300:10-25\\ =30-25\\ =5\\ c,17.\left[29-\left(-111\right)\right]+29.\left(-17\right)\\ =17.\left(29+111\right)+29.\left(-1\right).17\\ =17.\left(29+111-29\right)\\ =17.111=1887\\ d,19.43+\left(-20\right).43-\left(-40\right)\\ =19.43+\left(-20\right).43+40\\ =43.\left(19-20\right)+40\\ =-43+40\\ =-3\)

Tính [6,(29)32] : [2,(29)30]
Tính [6.(29)32]÷[2.(29)20]
\(\dfrac{29}{19}\cdot\dfrac{49}{51}+\dfrac{29}{19}\cdot\dfrac{34}{51}-\dfrac{29}{19}\cdot\dfrac{32}{51}\)
29/19.49/51+29/19.34/51-29/19.32/51
=29/19.(49/51+34/51-32/51)
=29/19.1

\(\dfrac{29}{19}.\dfrac{49}{51}+\dfrac{29}{19}.\dfrac{34}{51}-\dfrac{29}{19}.\dfrac{32}{51}\)
\(=\dfrac{29}{19}.\left(\dfrac{49}{51}+\dfrac{34}{51}-\dfrac{32}{51}\right)\)
\(=\dfrac{29}{19}.1\)
\(=\dfrac{29}{19}\)

29/19 . 49/51 + 29/19 . 34/51 - 29/19 . 32/51
= 29/19 .(49/51 + 34/51 - 32/51)
= 29/19 .(83/51 - 32/51)
= 29/19 . 51/51
= 29/19 . 1
= 29/19
