Mình chưa hiểu đề lắm nhưng chắc ý bạn là như này:
   \(87\frac{23}{59}+74\frac{17}{71}+12\frac{36}{59}+25\frac{5}{71}\)
= \(\left(87\frac{23}{59}+12\frac{36}{59}\right)+\left(25\frac{5}{71}+74\frac{17}{71}\right)\)
= \(\left(87+12\right)+\left(\frac{23}{59}+\frac{36}{59}\right)+\left(25+74\right)+\left(\frac{5}{71}+\frac{17}{71}\right)\)
= \(99+\frac{59}{59}+99+\frac{22}{71}\)
= \(198+1+\frac{22}{71}\)
= \(199\frac{22}{71}\)
Chúc bạn học tốt ^^!

hay doi hon so thanh phan  so de tinh cho de nhe

Bạn trả lời rõ đi

=27/51/59-7/51/59+1/3

=(27/51/59-7/51/59)+1/3

=20+1/3

=20/1/3

=31/6/13+5/9/41+(-36/6/13)

=(31/6/13+-36/6/13)+5/9/41

=-5+5/9/41

=9/41

duyet nha

a/=\(27\frac{51}{59}-7\frac{51}{59}+\frac{1}{3}\)

=20+\(\frac{1}{3}\)

=\(\frac{61}{3}\)

Các phân số theo thứ tự tăng dần :

\(\frac{12}{23};\frac{10}{19};\frac{20}{29};\frac{60}{71};\frac{15}{17}\)

Trả lời đầy đủ cho mk đc ko

49\(\frac{8}{23}\) - (5\(\frac{7}{32}\) + 14\(\frac{8}{23}\))

= 49\(\frac{8}{23}\) - 5\(\frac{7}{32}\) - 14\(\frac{8}{23}\)

= (49\(\frac{8}{23}\) - 14\(\frac{8}{23}\)) - 5\(\frac{7}{32}\)

= 35 - 5 - \(\frac{7}{32}\)

= 30 - \(\frac{7}{32}\)

= \(\frac{960}{32}\) - \(\frac{7}{32}\)

= 953/32

Câu b:

71\(\frac{38}{45}\) - (43\(\frac{8}{45}\) - 1\(\frac{17}{57}\))

= 71\(\frac{38}{45}\) - 43\(\frac{8}{45}\) - 1\(\frac{17}{57}\)

= 28\(\frac{30}{45}\) - 1\(\frac{17}{57}\)

= 28\(\frac23\) - 1\(\frac{17}{57}\)

= \(\frac{86}{3}\) - \(\frac{74}{57}\)

= \(\frac{1634}{57}\) - \(\frac{74}{57}\)

= \(\frac{1560}{57}\)

= \(\frac{520}{19}\)

chuc bn hoc gioi1

Ta có : \(\frac{1}{1000}+\frac{13}{1000}+\frac{25}{1000}+.....+\frac{85}{1000}+\frac{97}{1000}\)

\(=\frac{1+13+25+......+85+97}{1000}\)

\(=\frac{441}{1000}\)

12/23<10/19<20/29<60/71<15/17
