2/3 : 0,5 = 2/3 x 2 = 4/3
2/3 : 0,25 = 2/3 x 4 = 8/3
3/8 : 0,5 = 3/8 x 2 = 3/4
9/16 : 0,25 = 9/16 x 4 = 9/4
2/3 : 0,5 = 4/3
2/3 : 0,25 = 8/3
3/8 : 0,5 = 3/4
9/16 : 0,25 = 9/4
`25%+3/4+1/2:0,5-1/4:0,15+1/8:0,125`
`=1/4+3/4+1/2xx2-1/4xx4+1/8xx8`
`(1/4+3/4)+(1/2xx2)-(1/4xx4)+(1/8xx8)`
`=1+1-1+1`
`=2`
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0. 1
= 1 - 1 + 1 - 1
= 0 + 0
= 0
\(\frac{1}{2}:0,5-\frac{1}{4}:0,25+\frac{1}{8}:0,125-\frac{1}{10}:0,1\)
\(=\frac{1}{2}:\frac{1}{2}-\frac{1}{4}:\frac{1}{4}+\frac{1}{8}:\frac{1}{8}-\frac{1}{10}:\frac{1}{10}\)
\(=1-1+1-1=0\)
\(\dfrac{1}{10}+\dfrac{1}{2}:0,5-\dfrac{1}{4}:0,25+\dfrac{1}{8}:0,125\)
\(=\dfrac{1}{10}+\dfrac{1}{2}\times2-\dfrac{1}{4}\times4+\dfrac{1}{8}\times8\)
\(=\dfrac{1}{10}+1-1+1\)
\(=\dfrac{1}{10}+1=\dfrac{1}{10}+\dfrac{10}{10}=\dfrac{11}{10}\)
\(0,25.2\frac{1}{3}.30.0,5.\frac{8}{45}\)
\(=\frac{1}{4}.\frac{7}{3}.30.\frac{1}{2}.\frac{8}{45}\)
\(=\frac{14}{9}\)
\(0,25.2\frac{1}{3}.30.0,5.\frac{8}{45}\)
\(=0,25.\frac{7}{3}.30.0,5.\frac{8}{45}\)
\(=\frac{7}{12}.30.\frac{4}{45}\)
\(\frac{35}{2}.\frac{4}{45}\)
\(=\frac{14}{9}\)
