\(\dfrac{0.5+0.\left(3\right)-0.1\left(6\right)}{2.5+1.\left(6\right)-0.8\left(3\right)}\)
\(=\dfrac{\dfrac{1}{2}+\dfrac{1}{3}-\dfrac{1}{6}}{\dfrac{5}{2}+\dfrac{5}{3}-\dfrac{5}{6}}=\dfrac{1}{5}\)
a) 0,16 + 1,3
= \(\frac{4}{25}+\frac{13}{10}\)
= \(\frac{40}{250}+\frac{325}{250}\)
= \(\frac{73}{50}\)
b) 1,3 + 0,12 . \(2\frac{8}{11}\)
= \(\frac{13}{10}+\frac{3}{25}\times\frac{30}{11}\)
= \(\frac{13}{10}+\frac{18}{55}\)
= \(\frac{143}{110}+\frac{36}{110}\)
= \(\frac{179}{110}\)
c) 0,6 + 1,6
= \(\frac{3}{5}+\frac{8}{5}\)
= \(\frac{11}{5}\)
d) 3,6 + 1,36 \(\times\)\(2\frac{1}{5}\)
= \(\frac{18}{5}+\frac{34}{25}\times\frac{11}{5}\)
= \(\frac{18}{5}+\frac{374}{125}\)
= \(\frac{450}{125}+\frac{374}{125}\)
= \(\frac{824}{125}\)
0,(3)=\(\frac{3}{9}\)
0,1(6)=\(\frac{1}{6}\)
1,(6)=\(\frac{10}{6}\)
0,8(3)=\(\frac{5}{6}\)
tick nha
\(a,=\dfrac{4}{33}+\dfrac{1}{3}=\dfrac{5}{11}\\ b,=\dfrac{1}{6}-\dfrac{5}{3}+\dfrac{1}{2}=-1\)
A= (937.1 - 4.5) - (-4.5 + 37.1) -100
= (937-20) - 17 -100
= 917- 17-100
=900-100=800
