2,42 x 47 + 8 + 0,75 + 53 x 2,42 + 0,25 x 8
= 2,42 x (47 + 53) + 8 x (0,75 + 0,25)
= 2,42 x 100 + 8 x 1
= 242 + 8 = 250
\(2,42\) x \(47+8\) x \(0,75+53\) x \(2,42+0,25\) x \(8\)
\(=2,42\) x \(47+53\) x \(2,42\) + \(8\) x \(0,75+0,25\) x \(8\)
\(=2,42\) x \(\left(47+53\right)+8\) x \(\left(0,75+0,25\right)\)
\(=2,42\) x \(100+8\) x \(1\)
\(=242+8\)
\(=250\)
