X x 1,8 = 72
X = 72 : 1,8
X = 40
X x 0,34 = 1,19 x 1,02

a) x : 7 * 1,8 = 0,34
\(=>x:7\cdot\frac{9}{5}=\frac{17}{50}\)
\(=>x:7=\frac{17}{50}:\frac{9}{5}\)
\(=>x=\frac{17}{90}\cdot7\)
\(=>x=\frac{119}{90}\)
b) 1,5 : 4,5 * x = 2,5
\(=>\frac{3}{2}:\frac{9}{2}\cdot x=\frac{5}{2}\)
\(=>\frac{1}{3}\cdot x=\frac{5}{2}\)
\(=>x=\frac{5}{2}:\frac{1}{3}\)
\(=>x=\frac{15}{2}\)
