5/24

=\(\dfrac{7}{24}-\dfrac{2}{24}=\dfrac{5}{24}\)

=5/24

=(1124+1324)−(541+3641)+0,5=(1124+1324)−(541+3641)+0,5

$=1-1+0,5$

$=0,5$

   - \(\dfrac{5}{24}\) - ( \(\dfrac{16}{21}\) + 3)

=  - \(\dfrac{5}{24}\) - (\(\dfrac{16}{21}\) + \(\dfrac{63}{21}\))

= - \(\dfrac{5}{24}\) -  \(\dfrac{79}{21}\)

= -  \(\dfrac{667}{168}\)

-5-(24-x0)=-11

24-x0=-5-(-11)

24-x0=6

đến đây bạn có thể tự làm rồi nhỉ ?

chúc bạn hok tốt

a) 48, 96, 192, 384, 768

b) 19, 25, 32, 40, 49

c) 36, 51, 68, 89, 113

24 x (16 - 5) - 16 x ( 24 -5)

= 24.16 - 5.24 - 16.24 -5.16

= 24.(16-16) - 5(24-16)

= 0 - 5.8

= -40

sdfsdf

bạn mây giải cho đó rùi nha 

hok tốt

co can thiet the khong =)

Kết quả là 2 nha bạn. Mk ko the giải thích dc

\(\left(4-\frac{5}{12}\right):2+\frac{5}{24}\)

\(=\frac{43}{12}:2+\frac{5}{24}\)

\(=\frac{43}{24}+\frac{5}{24}\)

\(=\frac{48}{24}=2\)

5/12:25/24 =120/300 =2/5

5/12:25/24=2/5=0,4

\(\frac{2}{7}+\frac{7}{12}=\frac{24}{84}+\frac{49}{84}=\frac{73}{84}\)

\(\frac{25}{48}+\frac{22}{48}=\frac{47}{48}\)

\(\frac{5}{7}+\frac{3}{8}=\frac{40}{56}+\frac{21}{56}=\frac{61}{56}\)

\(\frac{15}{24}+\frac{15}{16}=15.\left(\frac{1}{24}+\frac{1}{16}\right)=\frac{25}{16}\)

\(\frac{5}{6}+\frac{3}{4}=\frac{20+18}{24}=\frac{19}{12}\)

\(\frac{9}{24}+\frac{14}{24}=\frac{23}{24}\)

học tót tích mình hem

2/7 + 7/12 = 73/84.

25/48 + 11/24 = 47/48.

5/7 + 3/8 = 61/56.

15/24 + 15/16 = 25/16.

5/6 + 3/4 = 19/12.

3/8 + 7/12 = 23/24.

hok tốt!

\(\frac{2}{7}+\frac{7}{12}=\frac{24}{84}+\frac{49}{84}=\frac{73}{84}\)

\(\frac{25}{48}+\frac{11}{24}=\frac{25}{48}+\frac{22}{48}=\frac{47}{48}\)

\(\frac{5}{7}+\frac{3}{8}=\frac{40}{56}+\frac{21}{56}=\frac{61}{56}\)

\(\frac{5}{6}+\frac{3}{4}=\frac{20}{24}+\frac{18}{24}=\frac{38}{24}=\frac{19}{12}\)

\(\frac{3}{8}+\frac{7}{12}=\frac{36}{96}+\frac{56}{96}=\frac{92}{96}=\frac{23}{24}\)

Học tốt
