Question

1/2 × 2/5 × 1/5 × 0,8 × 0,25 × 0,125

Answer 1

\(\frac{1}{2}x\frac{2}{5}x\frac{1}{5}x0,8x0,25x0,125\)

=\(\frac{1}{2}x\frac{2}{5}x\frac{1}{5}x\frac{4}{5}x\frac{1}{4}x\frac{1}{8}\)

=\(\frac{1x2x1x4x1x1}{2x5x5x5x4x8}\)

=\(\frac{1x1x1x1x1x1}{1x5x5x5x1x8}\)

=\(\frac{1}{1000}\)

Answer 2

\(\frac{1}{2}\times\frac{2}{5}\times\frac{1}{5}\times0,8\times0,25\times0,125\)

\(=0,5\times0,4\times0,2\times0,8\times0,25\times0,125\)

\(=\left(0,5\times0,2\right)\times\left(0,4\times0,25\right)\times\left(0,8\times0,125\right)\)

\(=0,1\times0,1\times0,1\)

\(=0,001\)
