a)\(\frac{13}{14}\) b)\(\frac{23}{42}\) c)\(\frac{41}{152}\)d)\(\frac{8575}{512}\)
mình chỉ biết làm bài 1 thôi
\(\frac{169}{182}=\frac{13}{14}\)
b,\(\frac{2323}{4242}\)=\(\frac{23}{42}\)
c,\(\frac{123123}{456456}\)=\(\frac{41}{152}\)
\(\frac{35\cdot54}{16\cdot49\cdot10}=\frac{27}{112}\)
2,,\(\frac{16}{36}=\frac{4}{9}\) \(\frac{20}{45}=\frac{4}{9}\) \(\frac{28}{63}=\frac{4}{9}\)
Vậy 3 phân số này bằng nhau.
b,\(\frac{45}{65}=\frac{9}{13}\) \(\frac{48}{52}=\frac{12}{13}\) \(\frac{2121}{1313}=\frac{21}{13}\)
Vậy phân số \(\frac{2121}{1313}\) lớn nhất
Hello bạn !
a)169/182=13.13/13.14=13/14
b)2323/4242=23.101/42.101=23/42
c)123123/456456=123.1001/456.1001=123/456
d)35.64/16.49.10=14/19
Bài 2:
a)16/36;20/45;28/63
=4/9;4/9;4;9
Vậy:4/9=4/9=4/9 hay 16/36=20/45=28/63
b)45/65;48/52;2121/1313
=9/13;12/13;21/13
Vậy:9/13<12/13<21/13 hay 45/65 < 48/52 < 21/13
a)\(\frac{12}{13}\)
b)\(\frac{23}{42}\)
c)\(\frac{27}{152}\)
hok tốt
B1 : 169/182 = 169:13/182:13 = 13/14
2323/4242 = 2323:101/4242:101 = 23/42
123123/456456 = 123123:3003/456456:3003 = 41/152
35*64/16*49*10 = 2240/7840 = 2240:1120/7840:1120 = 2/7
B2 : a)16/36 = 4/9 ; 20/25 = 4/9 ; 28/63 = 4/9
=> 4/9 = 4/9 = 4/9
b) 45/65 = 9/13 ; 48/52 = 12/13 ; 2121/1313 = 21/13
=> 9/13<12/13<21/13.
