\(\frac{15}{x}=\frac{25}{35}\)
\(\frac{15}{x}=\frac{15}{21}\)
\(\Rightarrow x=21\)
15/x = 25/35
15/x = 15/21
=> x = 21
Ủng hộ nhé !
\(\frac{15}{x}=\frac{25}{35}\)
\(\frac{25:5}{35:5}=\frac{5}{7}=\frac{15}{x}\)
\(\frac{5\times3}{7\times3}=\frac{15}{x}\)
Vậy x = 7 x 3 = 21
Đáp số : 21.
\(\frac{15}{X}=\frac{25}{35}\)
\(\frac{15}{X}=\frac{5}{7}\)
\(\frac{15}{X}=\frac{15}{21}\)
\(=>X=21\)
