\(x+3\frac{1}{2}+x=24\frac{1}{4}\)
\(x\times2+3,5=24,25\)
\(x\times2=24,25-3,5\)
\(x\times2=20,75\)
\(x=20,75:2\)
\(x=10,375\)
Vậy \(x=10,375\)
\(x+3\frac{1}{2}+x=24\frac{1}{4}\)
\(x.2+\frac{7}{2}=\frac{97}{4}\)
\(x.2=\frac{97}{4}-\frac{7}{2}\)
\(x.2=\frac{97}{4}-\frac{14}{4}\)
\(x.2=\frac{83}{4}\)
\(\Rightarrow x=\frac{83}{4}:2=\frac{83}{8}=10\frac{3}{8}\)
Vậy \(x=10\frac{3}{8}\)
Ủng hộ mk nha !!! ^_^
Mình cần gấp !
2) Tim x
a)x + 4\(\frac{1}{5}\)= 5 \(\frac{2}{3}\)× 10\(\frac{1}{2}\)
b)\(\frac{24}{5}\)- x =2\(\frac{1}{4}\): 1\(\frac{3}{4}\)
Tim x:
x X \(\frac{1}{2}\) + x X \(\frac{1}{4}\) + x X \(\frac{1}{8}\) =\(\frac{21}{24}\)
1. Tim x
x + \(3\frac{1}{2}\)= \(24\frac{1}{4}\)- x
Giai chi tiet giup minh nha minh se lay nick phu cua minh tick cho 6 tick len diem
\(\frac{\frac{1}{4}+\frac{1}{24}+\frac{1}{124}}{\frac{3}{4}+\frac{3}{24}+\frac{3}{124}}+\frac{\frac{2}{7}+\frac{2}{17}+\frac{2}{127}}{\frac{3}{7}+\frac{3}{17}+\frac{3}{127}}\)
tim x
1-(\(\frac{x}{5}\)+x-\(\frac{2}{3}\)) :\(\frac{3}{4}\)=0
x + \(3\frac{1}{2}+x=24\frac{1}{4}\)
GẤP GẤP GẤP !!!!!!!!!!!!!!
Tim x
x*\(\frac{5}{2}\)-x*\(\frac{3}{4}\)=\(\frac{11}{56}\)
B) Tim phan so \(\frac{a}{b}\)
\(\frac{a}{b}\)*\(\frac{2}{5}\)+\(\frac{1}{5}\)*\(\frac{a}{b}\)=\(\frac{1}{12}\)+\(\frac{1}{4}\)
Bài 1 Tim x
a,\(\frac{1}{2}:\frac{3}{7}+1\frac{1}{2}.1\frac{2}{3}:x=1\)
