\(4\frac{3}{4}+\left(-0,37\right)+\frac{1}{8}+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)
\(=4,75-0,37+0,125-1,28-2,5+\frac{37}{12}\)
\(=0,725+\frac{37}{12}\)
\(=\frac{457}{120}\)
\(4\frac{3}{4}+\left(-0,37\right)+\frac{1}{8}+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)
\(=4,75-0,37+0,125-1,28-2,5+\frac{37}{12}\)
\(=0,725+\frac{37}{12}\)
\(=\frac{457}{120}\)
Tính một cách hợp lý:
3\(\frac{4}{4}\)+ (-0,37) +\(\frac{1}{8}\)+ (-1,28) + (-2,5) + 3\(\frac{1}{12}\)
4\(\frac{3}{4}\) -0,37+\(\frac{1}{8}\)-1,28-2,5+3\(\frac{1}{12}\)
caccau giup mik nha
\(4\frac{3}{4}\)+(-0,37)+\(\frac{1}{8}\)+(-1,28)+(-2,5)+\(3\frac{1}{12}\)
\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)\)
\(4\frac{3}{4}+\left(-0,37\right)+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)
(giải giúp mình với)
Tính một cách hợp lí :
\(4\frac{3}{4}+\left(0,37\right)+\frac{1}{8}+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{2}\)
\(\frac{\frac{5}{22}+\frac{3}{13}-\frac{1}{2}}{\frac{4}{13}-\frac{2}{11}+\frac{3}{2}}\)
4/3/4+(-0,37)+1/8+(-1,28)+(-2,5)+3/1/12
4\(\frac{3}{4}\)+ ( - 0,37) +\(\frac{1}{8}\)+ ( - 1, 28 ) + ( - 2,5 ) + 3\(\frac{1}{12}\)
giúp mình với mình đang cần gấp
11 . tính tổng :
A, \(\frac{1}{9}\)+ 3,25 + \(5\frac{3}{16}\)+ \(4\frac{1}{3}\)+ 2,2 + 0,5
12 tính nhanh :
a, \(4\frac{3}{8}\)+ 0,37 + \(\frac{1}{8}\)+ 1,28 + 2,5 + \(3\frac{1}{12}\)
13 . tìm x biết :
a ) x + \(\frac{1}{3}\)= \(\frac{2}{15}\) b) x + \(\frac{2}{3}\)= \(\frac{3}{4}\)- \(\frac{1}{6}\)
tìm x
a)0,5.x-\(\frac{2}{3}\).x=\(\frac{7}{12}\) b)x:4\(\frac{1}{3}\)=-2.5
c)5,5.x=\(\frac{13}{15}\) d)(\(\frac{3x}{7}\)+1):(-4)=-\(\frac{-1}{28}\)
2)tính hợp lí
a)4\(\frac{3}{4}\)+(-0,37)+\(\frac{1}{8}\)+(-1,28)+(-2,5)+3\(\frac{1}{12}\)
b)
