Question

3/4+6,8+0,25+0,5+1/5+1/2

Answer 1

\(\frac{3}{4}+6,8+0,25+0,5+\frac{1}{5}+\frac{1}{2}\)

\(=0,75+6,8+0,25+0,5+0,2+0,5\)

\(=\left(0,75+0,25\right)+\left(6,8+0,2\right)+\left(0,5+0,5\right)\)

\(=1+7+1\)

\(=9\)

Answer 2

3/4+6.8+0.25+0.5+1/5+1/2 =9

Answer 3

3/4 + 6,8 + 0,25 + 0,5 + 1/5 + 1/2 = [ 3/4 + 6,8 ] + [ 1/5 + 0,25 ] + [ 0,5 + 1/2 ]

=1 + 7 + 1

= 9

Answer 4

\(\frac{3}{4}+6.8+0.25+0.5+\frac{1}{5}+\frac{1}{2}\)

\(=\frac{3}{4}+\frac{34}{5}+\frac{1}{4}+\frac{1}{2}+\frac{1}{5}+\frac{1}{2}\)

\(=\left(\frac{3}{4}+\frac{1}{4}\right)+\left(\frac{34}{5}+\frac{1}{5}\right)+\left(\frac{1}{2}+\frac{1}{2}\right)\)

\(=1+7+1\)

\(=9\)

Answer 5

  = \(\frac{3}{4}+\frac{6}{8}+0,25+0,5+\frac{1}{5}+\frac{1}{2}\)

  = \(0,75+0,75+0,25+0,5+0,2+0,5\)

  = \(2,95=\frac{59}{20}\)

Answer 6

\(\frac{3}{4}+6,8+0,25+0,5+\frac{1}{5}+\frac{1}{2}\)

\(=0,75+6,8+0,25+0,5+0,2+0,5\)

\(=0,75+0,25+6,8+0,2+0,5+0,5\)

\(=1+7+1\)

\(=9\)
