\(\frac{1}{3}\)Và đã ăn \(\frac{2}{3}\)

HT~

Moij người trả lời cho mình nhanh lên! Đang gấp lắm rồi

Gọi phân số đó là \(\frac{a}{b}\), ta có:

\(\frac{a}{b}\Leftrightarrow a\cdot b=308;a,b⋮2\)

\(\Rightarrow b=2\)

\(\Rightarrow a=308:2=154\)

Vậy phân số cần tìm là:

\(\frac{154}{2}\)

1200

ht

\(25\times5\times4\times3=\left(25\times4\right)\times\left(5\times3\right)\)

\(=100\times15=1500\)

Ta có:

\(\frac{52}{76}=\frac{52:4}{76:4}=\frac{13}{19};\frac{1313}{1919}=\frac{1313:101}{1919:101}=\frac{13}{19}\)

Vì\(\frac{13}{19}=\frac{13}{19}\)nên\(\frac{52}{76}=\frac{1313}{1919}\)

@phamcongquy

100 - 10 + 10 - 100

= 90 + 10 - 100

= 100 - 100

= 0

Chúc bạn học tốt.

= 320 nhé 

nhớ t i c k 

@phamcongquy

6 * ( 78 + 2) - 160= 320 

\(\frac{4}{x+1}=\frac{12}{9}\)
\(\frac{4}{x+1}=\frac{4}{3}\)

x + 1 = 4 :\(\frac{4}{3}\)

x + 1 = 3

x = 3 - 1

x = 2

Chúc bạn học tốt.
