bằng 23/49 nhé mình với

23/49 nha bạn

TL

\(\frac{232323}{494949}=\frac{23.10101}{49.10101}\)

\(=\frac{23}{49}\)

HT

\(\dfrac{23}{49}\)

=23/49 nha

HT

má ơi sao mà giải đc

1/3 ; 1/2 ; 5/9 ; 23/49

a, - 151515 / 232323 = -15/23

b, 1.2.3 + 2.4.6 + 4.8.12 / 1.3.5 + 2.4.6 + 4.12.20 

= 146/341

1313/1717 = ( 1313 :101)/(1717:101)=13/17

171717/191919=(171717:10101)/(191919:10101)=17/19

231231/343343=(231231:7007)/(343343:7007)=33/49

373737/494949=(373737:10101)/(494949:10101)=37/49

\(\frac{232323}{494949}=\frac{232323:10101}{494949:10101}=\frac{23}{49}\)

\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)

\(\frac{171171171}{180180180}=\frac{171171171:9009009}{180180180:9009009}=\frac{19}{20}\)

\(\frac{232323}{494949}=\frac{232323:10101}{494949:10101}=\frac{23}{49}\)

\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)

\(\frac{171171171}{180180180}=\frac{171171171::9009009}{180180180:9009009}=\frac{19}{20}\)

Không.Rút gọn được bạn nhé

\(\dfrac{60}{72}=\dfrac{60:12}{72:12}=\dfrac{5}{6}\\ \dfrac{70}{95}=\dfrac{70:5}{95:5}=\dfrac{14}{19}\\ \dfrac{150}{360}=\dfrac{150:30}{360:30}=\dfrac{5}{12}\)

\(\dfrac{60}{72}=\dfrac{5}{6}\)

\(\dfrac{70}{95}=\dfrac{14}{19}\)

\(\dfrac{150}{360}=\dfrac{5}{12}\)

a: Các phân số tối giản là \(\dfrac{1}{3};\dfrac{4}{7};\dfrac{72}{73}\) vì ƯCLN(1;3)=1; ƯCLN(4;7)=1; ƯCLN(72;73)=1

b:

Các phân số rút gọn được là

 \(\dfrac{8}{12}=\dfrac{8:4}{12:4}=\dfrac{2}{3}\)

\(\dfrac{30}{36}=\dfrac{30:6}{36:6}=\dfrac{5}{6}\)

a) Phân số đã cho chưa tối giản

\(\dfrac{27}{123}=\dfrac{9\cdot3}{41\cdot3}=\dfrac{9}{41}\)

b) Phân số đã cho chưa tối giản

\(\dfrac{33}{77}=\dfrac{3\cdot11}{7\cdot11}=\dfrac{3}{7}\)

a, \(\dfrac{27}{123}=\dfrac{9}{41}\)

b, \(\dfrac{33}{77}=\dfrac{3}{7}\)
