6/25=6x4/25x4=24/100
500/1000=500:10/1000:10=50/100
18/200=18:2/200:2=9/100
tick nha
x + \(\frac{7}{12}\)= \(\frac{17}{18}\)- \(\frac{1}{8}\)
x + \(\frac{7}{12}\)= \(\frac{7}{8}\)
x = \(\frac{7}{8}\)- \(\frac{7}{12}\)
x = \(\frac{7}{24}\)
\(\frac{105}{50}=2\frac{5}{50}\),\(\frac{62}{25}=2\frac{12}{25}\),\(\frac{18}{8}=2\frac{2}{8}\),\(\frac{52}{40}=1\frac{1}{40}\),\(\frac{62}{20}=3\frac{2}{20}\),\(\frac{36}{11}=3\frac{3}{11}\),\(\frac{72}{25}=2\frac{22}{25}\)
Chúc bạn học tốt
105/50 =2 1/10 ,
62/25 = 2 12/25
18/8 = 2 1/4
52/40 = 1 3/10
62/20 = 3 1/10
36/11 = 3 3/11
72 /25 = 2 22/25
\(\frac{25-x}{18}=\frac{1}{2}\)
\(\frac{25-x}{18}=\frac{9}{18}\)
\(25-x=9\)
\(x=25-9\)
\(x=16\)
\(\frac{25-x}{18}=\frac{1}{2}\)
\(\frac{25-x}{18}=\frac{9}{18}\)
\(\Rightarrow25-x=9\)
\(x=25-9\)
\(x=16\)
