bằng 23/49 nhé mình với

23/49 nha bạn

TL

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

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

HT

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

\(\dfrac{232323}{494949}=\dfrac{23}{49}\)

chúc bạn học tốt!

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

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

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

a, 18/54 = 1/3 

b, 1/3 = 1/5 +2/15

a) \(\frac{18}{54}=\frac{1}{3}\)

b) \(\frac{18}{54}=\frac{1}{5}+\frac{2}{15}\)

~Học tốt~

a. Mẫu số chung nhỏ nhất là 24

b. \(\dfrac{5}{7}\)

c. \(\dfrac{3}{4}\)

d. \(\dfrac{9}{12}\) và giữ nguyên phân số còn lại

e. \(\dfrac{3}{6};\dfrac{4}{6};\dfrac{5}{6}\)

g. \(\dfrac{9}{12};\dfrac{4}{12};\dfrac{2}{12}\)

h. \(\dfrac{15}{60};\dfrac{20}{60};\dfrac{12}{60}\)

i. \(\dfrac{10}{1}\)

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

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